I have posted another crash without debugging symbols in https://lists.gnu.org/archive/html/emacs-devel/2024-11/msg00724.html. This time, I was running emacs in gdb, the trace is below. Seems to be related to bug#38936.

Hi,

I am experiencing crashes during GC, and I have= no idea what causes these crashes or how to reproduce them consistently. I= have posted another crash without debugging symbols in https://lists= .gnu.org/archive/html/emacs-devel/2024-11/msg00724.html. This time, I w= as running emacs in gdb, the trace is below. Seems to be related to bug#389= 36.

I'm not sure this is related to bug#38936: that one seemed to be fixed, and there's no process_mark_stack in the backtrace there. But maybe this is indeed the same problem. > (gdb) bt full > #0 vector_marked_p (v=v@entry=0x4000000023000008) at alloc.c:4273 Please show the details of 'v'. Like this: (gdb) frame 0 (gdb) p v (gdb) p/x v->header Also, you've elided the part where GDB says what fatal signal was delivered. I'm guessing it was SIGSEGV, but please show that part of what GDB displayed when it kicked in.

Also, what is the memory footprint of the crashed Emacs process? > In GNU Emacs 30.1 (build 1, x86_64-pc-linux-gnu, X toolkit, cairo > version 1.18.2, Xaw3d scroll bars) > Windowing system distributor 'The Cygwin/X Project', version 11.0.12000000 > System Description: Red Hat Enterprise Linux 8.10 (Ootpa) Does this mean you run Emacs on a Red Hat system via the Cygwin X implementation that runs on Windows? Anything else that is "unusual" in your sessions? Please don't save us any such details, as they might be relevant, or provide important clues as to where to look for the causes. Thanks.

If you can reproduce it at all, we probably need a live gdb session or (slightly worse) a core dump to debug this further, because not all information is in the backtrace. > I have posted another > crash without debugging symbols in https://lists.gnu.org/archive/html/ema= cs-devel/2024-11/msg00724.html. This time, I was running emacs in gdb, the > trace is below. Seems to be related to bug#38936. Are you capturing coredumps ("gcore" in gdb after the crash; it's best to do this even if you keep the gdb session alive) or keeping the gdb sessions alive? That would help provide further information which might allow us to track this down. In particular, last_marked and last_marked_index would be very interesting. > (gdb) bt full > #0 vector_marked_p (v=3Dv@entry=3D0x4000000023000008) at alloc.c:4273 > No locals. > #1 0x00000000005892bc in process_mark_stack (base_sp=3Dbase_sp@entry=3D2= 188) at alloc.c:7276 > ptr =3D 0x4000000023000008 > pvectype =3D > obj =3D 0x400000002300000d That's a pseudovector header (for a font spec), but we've mistaken it for a Lisp object. The most likely reason is that a vector was freed and partly re-used for this pseudovector, but it was still reachable somehow, and we tried accessing it again after it was freed. We need to look at last_marked, to find out which of the 76 slots in a buffer object contained (directly or indirectly) this stale object, and then try to figure out how it got there. > Configured using: > 'configure > --prefix=3D/nix/store/xdxaa55akicvs3jjrr8d7nmzla4gzbyl-emacs-30.1 > --disable-build-details --with-modules --with-x-toolkit=3Dlucid > --with-cairo --without-xft --with-compress-install > --with-toolkit-scroll-bars --with-native-compilation > --without-imagemagick --with-mailutils --without-small-ja-dic > --with-tree-sitter --with-xinput2 --without-xwidgets --with-dbus > --with-selinux' I've looked a little at unusual code which would be enabled by this configuration, but apart from this strangeness in x_default_scroll_bar_color_parameter, I couldn't find anything: AUTO_STRING (foreground, "foreground"); AUTO_STRING (background, "foreground"); I suspect no one's using X resources to set the background color of scroll bars...

Can you describe what you were doing at the time of the crash?
=

I was not doing anything in particular (editing a latex= file with LaTeX/PS mode). These crashes have happened to me at very random= times. The only thing that I have been suspecting could be causing this is= viewing org-mode buffers that have special fontification. I have=C2=A0https://github.com/awth13/org-= appear and https://gith= ub.com/minad/org-modern installed, and previously I had https://github.com/integral-= dw/org-superstar-mode. I had just viewed an org file before the crash.<= /div>

Please show the details of 'v'.=C2=A0 Like this:

=C2=A0 (gdb) frame 0
=C2=A0 (gdb) p v
=C2=A0 (gdb) p/x v->header

Also, you've elided the part where GDB says what fatal signal was
delivered.=C2=A0 I'm guessing it was SIGSEGV, but please show that part= of
what GDB displayed when it kicked in.

Please keep the crashed session inside GDB in case we want you to look
around and report more data.

Unfortunately, I don't have the pr= ogram running (because I foolishly thought I could continue from the crash)= . I do have the core however, here is what you both asked for:
Program terminated with = signal SIGSEGV, Segmentation fault.

This part seems to indicate you run something called
gcmh-idle-garbage-collect, which triggers GC from a timer function?
If so, please describe what you do with this and show the relevant
code.

In general, please describe anything related to GC and timers that you
customized in your sessions, as that could be relevant to the nature
and the reasons of this bug.


Yes, I am using gcmh (https://github.com/emac= smirror/gcmh/blob/master/gcmh.el). I have these parameters for it:

(setq gcmh-idle-= delay 'auto =C2=A0; default is 15s
=C2=A0 =C2=A0 =C2=A0 gcmh-auto-id= le-delay-factor 10
=C2=A0 =C2=A0 =C2=A0 gcmh-high-cons-threshold (* 64 1= 024 1024)) =C2=A0; 64mb

I don't thi= nk that there is anything else GC related that I am using.

Also, what is the memory footprint of the crashed Emacs process?

Hard for me to say. I restored my sess= ion and this is the memory-report for that session. I would assume that the= crashed session is 2-3 times larger:

Does this mean you run Emacs on a Red Hat system via the Cygwin X

=C2=A0
Correct.

Anything else that is "unusual" in your sessions?=C2= =A0 Please don't save
us any such details, as they might be relevant, or provide important
clues as to where to look for the causes.


In particular, last_marked and last_marked_index would be very
interesting.

=C2=A0I have included that in the gdb trace above. Please, let me know if= there is anything else I can dig out from the core.

Thanks!

If you can reproduce it at all, we probably need a live gdb session or
(slightly worse) a core dump to debug this further, because not all
information is in the backtrace.

Are you capturing coredumps ("gcore" in gdb after the crash; it&#= 39;s best
to do this even if you keep the gdb session alive) or keeping the gdb
sessions alive?=C2=A0 That would help provide further information which mig= ht
allow us to track this down.

In particular, last_marked and last_marked_index would be very
interesting.

That's a pseudovector header (for a font spec), but we've mistaken = it
for a Lisp object.=C2=A0 The most likely reason is that a vector was freed<= br> and partly re-used for this pseudovector, but it was still reachable
somehow, and we tried accessing it again after it was freed.

We need to look at last_marked, to find out which of the 76 slots in a
buffer object contained (directly or indirectly) this stale object, and
then try to figure out how it got there.

I've looked a little at unusual code which would be enabled by this
configuration, but apart from this strangeness in
x_default_scroll_bar_color_parameter, I couldn't find anything:

=C2=A0 =C2=A0 =C2=A0 AUTO_STRING (foreground, "foreground");
=C2=A0 =C2=A0 =C2=A0 AUTO_STRING (background, "foreground");

I suspect no one's using X resources to set the background color of

So we probably dumped a compiled unit's data, then returned to the vectors or pseudovectors, which would be interesting. Can you provide the output of: p *XVECTOR(0x98e79dd) x/32gx $.contents p *XVECTOR(0x98f1d0d) x/32gx $.contents > Also, what is the memory footprint of the crashed Emacs process? > > Hard for me to say. I restored my session and this is the memory-report f= or that session. I would assume that the crashed session is 2-3 times large= r: The size of the core file might provide a good ballpark number. "objdump -h /path/to/core" may reveal even more about how much memory was in use. > Does this mean you run Emacs on a Red Hat system via the Cygwin X > implementation that runs on Windows? > > Correct. Can you say more about that? Are you running using a remote X server, or some kind of tunnel setup, or is this some sort of WSL or VM setup? It's relevant because remote X sessions have very different timing characteristics, and different code for determining mouse positions is in use. Can you also include the output of p *terminal_list->display_info and as much of the output of p *terminal_list->display_info.x as you're comfortable with (x_id_name might be something you would want to redact), as well as p Vx_use_fast_mouse_position Background: I have a vague hunch that commit ced135ebdbfb0eea719ce165a454e7ff0b681e88 is part of the problem. This replaced the staticpro'd global variable last_mouse_scroll_bar by an element of dpyinfo (with the same name) which does not appear to be protected from GC. (The same is true of the last_mouse_frame, last_mouse_glyph_frame, last_mouse_motion_frame, x_pending_autoraise_frame elements of dpyinfo, and a few others... I don't understand why these aren't GC-protected, and there is no comment clearly explaining they shouldn't be, so we could try adding protection to them and seeing whether that fixes the crashes). Thank you, and sorry for requesting so much information!

The size of the core file might provide a good ballpark number.

The output of obdjump is very large:

Can you say more about that?=C2=A0 Are you running using a remote X server,=
or some kind of tunnel setup, or is this some sort of WSL or VM setup?
It's relevant because remote X sessions have very different timing
characteristics, and different code for determining mouse positions is
in use.

This is not WSL or VM. I use PUTTY on = Windows 10 to connect to a remote Linux host (which is running the emacs da= emon), and then I open the emacs frame (emacsclient) with X forwarding usin= g Cygwin/X.

Thank you! Unfortunately, the buffer object itself is not contained

>=C2=A0 Does this mean you run Emacs on a Red Hat system via the Cygwin = X

It's relevant because remote X sessions have very different timing

Can you also include the output of

and as much of the output of

=C2=A0 =C2=A0 p *terminal_list->display_info.x

as you're comfortable with (x_id_name might be something you would want=

=C2=A0 =C2=A0 p Vx_use_fast_mouse_position

Background: I have a vague hunch that commit

replaced the staticpro'd global variable last_mouse_scroll_bar by an element of dpyinfo (with the same name) which does not appear to be
protected from GC.=C2=A0 (The same is true of the last_mouse_frame,
last_mouse_glyph_frame, last_mouse_motion_frame,
x_pending_autoraise_frame elements of dpyinfo, and a few others...=C2=A0 I<= br> don't understand why these aren't GC-protected, and there is no com= ment
clearly explaining they shouldn't be, so we could try adding protection=

Can you try this (subtracting 5 from the tagged pointer to get the base
pointer, then printing its memory region):

=C2=A0 =C2=A0 =C2=A0x/32gx 0x98e79d8
=C2=A0 =C2=A0 =C2=A0x/32gx 0x98f1d08

Unfortunately, I don't see any overlap between that and the last_marked=
entries.=C2=A0 Might have worked with an even larger LAST_MARKED_SIZE.

No dangling pointers here, as far as I can see.

>=C2=A0 Can you say more about that?=C2=A0 Are you running using a remot= e X server,
>=C2=A0 or some kind of tunnel setup, or is this some sort of WSL or VM = setup?
>=C2=A0 It's relevant because remote X sessions have very different = timing

Thank you, that makes sense!

This tells us the stale pointer was most likely found in a hash table,

of this?

Unfortunately, most likely, all that is going to tell us the basic types of the keys and values in the hash table, and we're then going to have<= br> to investigate the surviving keys and values to get a clue as to what
the hash table might have been.=C2=A0 Unless someone can think of a better<= br> way?

Presumably 0x98e7985 is the native comp unit and 0x8f680f4 is its file name, so could you please run p *(char **)0x8f68108 to retrieve it, as well as x/32gx 0x9e7980 to confirm it is (or was) a native comp unit? Going back through the last_marked array, it seems we're looking at the 'function-history plist property of a symbol at 0x15554df1a3a0, but I'm not sure which of the strings we mark after that is its name. Best to print all of them: p *(char **)0x8ae5588 p *(char **)0x15554ec0ff98 p *(char **)0x15554ec0ff78 The last vector or pseudovector we marked before that was 0x38294cd, so I think we should look at x/32gx 0x38294c8 too. > Keep them coming! Are you still suspecting X? Currently, it seems more likely to involve the nativecomp code, but I've stared at it for a while and I don't see how it can resurrect comp units once they become unreachable. Thanks again!

That's a native comp unit's lambda_gc_guard_h, which is quite curio= us.
Presumably 0x98e7985 is the native comp unit and 0x8f680f4 is its file
name, so could you please run

=C2=A0 =C2=A0 p *(char **)0x8f68108

to retrieve it, as well as

=C2=A0 =C2=A0 x/32gx 0x9e7980

to confirm it is (or was) a native comp unit?

Going back through the last_marked array, it seems we're looking at the=
'function-history plist property of a symbol at 0x15554df1a3a0, but I&#= 39;m
not sure which of the strings we mark after that is its name.=C2=A0 Best to=
print all of them:

=C2=A0 =C2=A0 p *(char **)0x8ae5588
=C2=A0 =C2=A0 p *(char **)0x15554ec0ff98
=C2=A0 =C2=A0 p *(char **)0x15554ec0ff78

The last vector or pseudovector we marked before that was 0x38294cd, so
I think we should look at

=C2=A0 =C2=A0 x/32gx 0x38294c8

too.

> Keep them coming! Are you still suspecting X?

Currently, it seems more likely to involve the nativecomp code, but I'v= e
stared at it for a while and I don't see how it can resurrect comp unit= s
once they become unreachable.

Thanks again!

The good news is I found *a* nativecomp GC bug, but I'm not convinced it's related to the one you've been seeing. It works only with the right optimization options (-O2 here), because without optimization conservative GC will save the day, but that matches your build. Create a file like this: ;;; -*- lexical-binding: t; -*- (defun f () (fmakunbound 'f) (garbage-collect) (lambda () nil)) then execute: (prog1 nil (native-elisp-load (native-compile "file.el"))) (funcall 'f) What will happen is that while execution is in 'f', there is no reference to the subr f (the backtrace only keeps alive the symbol f, not the subr f, and funcall_general is tail recursive so its stack variables are out of scope by the time we call garbage-collect). That means the compilation unit may get unloaded while we're still in 'f', and then we crash trying to return to it after garbage collection. I *think* that if there were a second handle keeping alive the dynlib (but not the compilation unit), we would return an anonymous lambda which would refer to the now-invalid (but still open) native compilation unit. This would also happen if dlclose failed to unload the library. I've been able to simulate this by intercepting dynlib_close and returning from it immediately (without actually closing the shared object) and executing: (prog1 nil (native-elisp-load (native-compile "file.el"))) (prog1 nil (setq x (funcall 'f))) This succeeded, and when I tried to access 'x' I got a crash, as expected. At this point, the bug seems a little contrived, because it's unusual for a function to fmakunbound the symbol it is bound to, but I think that's pretty much what happens in some recursive load scenarios. If the function redefines itself using (ultimately) defalias, the old function value is sometimes, but not always, stored in the function-history symbol property. I don't believe this mechanism reliably keeps alive the old function (and, thus, the compilation unit) either, and it can be circumvented entirely by using Ffset directly. Again, this is unlikely to be precisely what happened to George here, but it indicates that relying on the current specpdl backtrace to keep alive subrs that are being called doesn't work in all cases. We should probably keep the actual subr around, either in a (hidden?) backtrace slot somewhere or in a local variable in funcall_subr which we ensure cannot be optimized away (by tail recursion or otherwise). Note that the second dynlib handle isn't required for a crash, but the crashes we see without it should be immediate, upon returning from GC, assuming dynlib_close actually synchronously unmaps the library. I think both the symbol being bound to something else and the second handle might happen "naturally" during some recursive reload scenarios. > (gdb) p *(char **)0x8f68108 > $1 =3D 0x2018b608 "/nix/store/xdxaa55akicvs3jjrr8d7nmzla4gzbyl-emacs-30.1= /lib/emacs/30.1/native-lisp/30.1-1ed0c1e8/cl-print-79bf9fb1-14d0e7d5.eln" > (gdb) x/32gx 0x9e7980 Oops, I messed up there.

How reproducible did you say this crash was?

I get it around once a month I would say.

<= div>My elisp is way too primitive to be able to understand the circumstance= s that lead to the bug you are describing, but I did find an instance of fm= akunbound in a macro in Doom emacs:=C2=A0https://github.com/doomemacs/doomemacs/blob/66f1b25dac30ca97779e8= a05e735e14230556492/lisp/doom-lib.el#L442

Can&= #39;t really say if it's triggering the bug that you are describing, th= ough.

Thanks!

Thanks again!

The good news is I found *a* nativecomp GC bug, but I'm not convinced it's related to the one you've been seeing.=C2=A0 It works only wit= h the
right optimization options (-O2 here), because without optimization
conservative GC will save the day, but that matches your build.

Create a file like this:

;;; -*- lexical-binding: t; -*-

(defun f ()
=C2=A0 (fmakunbound 'f)
=C2=A0 (garbage-collect)
=C2=A0 (lambda () nil))

then execute:

(prog1 nil (native-elisp-load (native-compile "file.el")))
(funcall 'f)

What will happen is that while execution is in 'f', there is no
reference to the subr f (the backtrace only keeps alive the symbol f,
not the subr f, and funcall_general is tail recursive so its stack
variables are out of scope by the time we call garbage-collect).=C2=A0 That=
means the compilation unit may get unloaded while we're still in 'f= ',
and then we crash trying to return to it after garbage collection.

I *think* that if there were a second handle keeping alive the dynlib
(but not the compilation unit), we would return an anonymous lambda
which would refer to the now-invalid (but still open) native compilation unit.=C2=A0 This would also happen if dlclose failed to unload the library.=

I've been able to simulate this by intercepting dynlib_close and
returning from it immediately (without actually closing the shared
object) and executing:

(prog1 nil (native-elisp-load (native-compile "file.el")))
(prog1 nil (setq x (funcall 'f)))

This succeeded, and when I tried to access 'x' I got a crash, as expected.

At this point, the bug seems a little contrived, because it's unusual for a function to fmakunbound the symbol it is bound to, but I think
that's pretty much what happens in some recursive load scenarios.=C2=A0= If
the function redefines itself using (ultimately) defalias, the old
function value is sometimes, but not always, stored in the
function-history symbol property.=C2=A0 I don't believe this mechanism<= br> reliably keeps alive the old function (and, thus, the compilation unit)
either, and it can be circumvented entirely by using Ffset directly.

Again, this is unlikely to be precisely what happened to George here,
but it indicates that relying on the current specpdl backtrace to keep
alive subrs that are being called doesn't work in all cases.

We should probably keep the actual subr around, either in a (hidden?)
backtrace slot somewhere or in a local variable in funcall_subr which we ensure cannot be optimized away (by tail recursion or otherwise).

Note that the second dynlib handle isn't required for a crash, but the<= br> crashes we see without it should be immediate, upon returning from GC,
assuming dynlib_close actually synchronously unmaps the library.

I think both the symbol being bound to something else and the second
handle might happen "naturally" during some recursive reload scen= arios.

Oops, I messed up there.=C2=A0 I meant x/32gx 0x98e7980, though it's no=
longer necessary (we know it's a native compilation unit because it
appears in the right slot in the subr below).

That's the beginning of the function-history of the cl-prin1 symbol
(while symbols mark the strings containing their names, they do not put
the marked string in last_marked, so we have to deduce this from the
docstring).

that appears to be the cl-prin1 definition (minargs 1, maxargs 2, native comp unit 0x98e7985).

How reproducible did you say this crash was?=C2=A0 Unless we can come up wi= th
a convincing alternative explanation, it may be worth it to fix
funcall_subr to avoid this particular bug, and keep running Emacs in gdb until it crashes again...

I haven't had a chance to apply Pip's patch, so this is just 30.1 as before. The trace looks a bit different, apologies if it's a different issue. I still have the program under gdb. I have redacted the frames after the emacs_abort in the full backtrace, let me know if you need anything from them, or what other information I can provide from gdb. I did not use any org-mode stuff, so my original hunch. The only unusual (from me) thing I did just before the crash was open up an eshell buffer, execute a couple of commands, and close it. I hadn't used eshell-mode before that in that session. Thanks!

I got another crash, again in GC. I haven't had a= chance to apply Pip's patch, so this is just 30.1 as before. The trace= looks a bit different, apologies if it's a different issue. I still ha= ve the program under gdb. I have redacted the frames after the emacs_abort = in the full backtrace, let me know if you need anything from them, or what = other information I can provide from gdb.

I did no= t use any org-mode stuff, so my original hunch. The only unusual (from me) = thing I did just before the crash was open up an eshell buffer, execute a c= ouple of commands, and close it. I hadn't used eshell-mode before that = in that session.

Thanks!
George

Can you check whether eln files were created just before the crash? Over here, the relevant command would be $ ls -Strl ~/.emacs.d/eln-cache/*/* and looking at the last few lines to see whether any files have the creation date in the right range (after you started using eshell but before the crash happened). > (gdb) set print elements 0 > (gdb) bt full > .....

We tried marking, most likely, the vectorlike starting at 0x196922b0, and ended up trying to mark 0xffdf6e1, which is not a valid Lisp_Object because it uses the unused tag. (What confuses me is that pp > end in frame #54, but we're inside a loop which reads: for (pp =3D start; (void const *) pp < end; pp +=3D GC_POINTER_ALIGNMENT) { void *p =3D *(void *const *) pp; mark_maybe_pointer (p, false); ... } Debugging information in optimized builds isn't always perfectly reliable, so it might just be that). So we first should inspect the memory around 0x196922b0 to find out whether it looks like a valid vector block, and whether the bad word was in this block or in the string object marked just before. I'd suggest running x/32gx 0x196922b0 to look at the memory following the pointer, and x/32gx 0x19692200 to get some idea of whether it might be the middle of a vectorlike. You could try running p mem_find (0x196922b5) p *$ to see where the vector block (if it is one) was supposed to start. (There's a slight chance this will crash). It may be worth it to print the entire vector block, which should be doable by running x/512gx $.start after that command. > (gdb) p last_marked_index > $4 =3D 28 > (gdb) p last_marked > $5 =3D {0x18e5e015, 0x3b0b4753, 0x7699356d, 0x249d0a33, 0x6dc36f23, 0x6dc= 36f23, 0x15554df37b68, 0x7699356d, 0x15554df3e0a8, 0x7cfa99b5, > 0x7699356d, 0x15554ec33b75, 0x15554ec33b75, 0xceb350, 0x15554ec33b75, 0x1= 5554df3dfe0, 0x15554ec33b75, 0x15554ec336fd, 0x249d0d13, > 0x15554ec336fd, 0x15554df3dfe0, 0x7699356d,=20 > 0x15554ec3321d, 0x7699356d, 0x196922b5, 0x406, 0x15554efc8fac, 0xffdf6e= 1, 0x269b51f3, 0x17baf00, 0x269b5203, 0x285dedb4, 0x7, 0x0, 0x7 That gives us some more context. Before hitting our bad object, we marked 0x406, then 0x15554efc8fac. 0x406 is the Lisp_Object representation of 257 (0x0101), and that number is used extensively in bytecode output: bytecode objects with minargs =3D maxargs =3D 1 look like this: #[257 "...bytecode..." [constants...] ...] This means that 0x15554efc8fac is most likely the string containing the bytecode; could you please run p *(struct Lisp_String *)0x15554efc8fa8 to see whether this is true, and whether any data is still there? It would be interesting to know whether we were marking the string or the bytecode object when the crash happened; please run p mark_stk p mark_stk.stack[0] p mark_stk.stack[1] p mark_stk.stack[2] so we see how deep in the mark stack we were at the time. Thanks!

Really appreciate you putting so much effort into this. See below for what you asked for. George It's a good idea to use "gcore" to generate a core file from gdb, just > in case the session is destroyed. Done. Can you check whether eln files were created just before the crash? > Over here, the relevant command would be > > $ ls -Strl ~/.emacs.d/eln-cache/*/* > > and looking at the last few lines to see whether any files have the > creation date in the right range (after you started using eshell but > before the crash happened). > Nothing in the directory ( /u/panagopo/.config/emacs/.local/cache/eln/30.1-1ed0c1e8 for me) that is on the same day of the crash. In fact, eshell isn't there at all, which probably makes sense as I am using the built-in version, so it was already natively-compiled. So we first should inspect the memory around 0x196922b0 to find out > whether it looks like a valid vector block, and whether the bad word was > in this block or in the string object marked just before.

Thanks, Pip! Really appreciate you putting so much ef= fort into this. See below for what you asked for.

Done.

Can you check whether eln files were created just before the crash?
Over here, the relevant command would be

$ ls -Strl ~/.emacs.d/eln-cache/*/*

and looking at the last few lines to see whether any files have the
creation date in the right range (after you started using eshell but
before the crash happened).

Nothing in the directory ( /u/panagopo/.config/emacs/.= local/cache/eln/30.1-1ed0c1e8 for me) that is on the same day of the crash.= In fact, eshell isn't there at all, which probably makes sense as I am= using the built-in version, so it was already natively-compiled.

=C2=A0 So we first should inspect the memory around 0x196922b0 to find out
whether it looks like a valid vector block, and whether the bad word was in this block or in the string object marked just before.=C2=A0 I'd sug= gest
running

=C2=A0 =C2=A0 x/32gx 0x196922b0

to look at the memory following the pointer, and

=C2=A0 =C2=A0 x/32gx 0x19692200

to get some idea of whether it might be the middle of a vectorlike.

You could try running

=C2=A0 =C2=A0 p mem_find (0x196922b5)
=C2=A0 =C2=A0 p *$

to see where the vector block (if it is one) was supposed to start.
(There's a slight chance this will crash). It may be worth it to print<= br> the entire vector block, which should be doable by running

=C2=A0 =C2=A0 x/512gx $.start

after that command.

This means that 0x15554efc8fac is most likely the string containing the
bytecode; could you please run

=C2=A0 =C2=A0p *(struct Lisp_String *)0x15554efc8fa8

to see whether this is true, and whether any data is still there?

It would be interesting to know whether we were marking the string or
the bytecode object when the crash happened; please run

=C2=A0 =C2=A0p mark_stk
=C2=A0 =C2=A0p mark_stk.stack[0]
=C2=A0 =C2=A0p mark_stk.stack[1]
=C2=A0 =C2=A0p mark_stk.stack[2]

so we see how deep in the mark stack we were at the time.

(gdb) p *(struct Lisp_String *)0x15554= efc8fa8

Not only is that word not a Lisp object, it doesn't ring any bells at all - it's just below 256 MB if it's in bytes. I'm not sure whether your memory layout places anything there, and even if it did it would be a strangely unaligned address. Just in case, can you run: x/32gx 0xffdf600 p $rsp Have you customized anything to 256 MB, precisely or approximately? What are your values for gcmh-high-cons-threshold and gcmh-low-cons-threshold, assuming that was in use during the crash? Can you also try: p globals.f_gc_cons_threshold p globals.f_string_chars_consed p &globals.f_gc_cons_threshold The rest of the memory dump looks normal; the other bytecode closures in the block are fine. I must confess that it looks at this point like some random C code (we know it's not Lisp, at least) wrote a single word that doesn't ring any bells to a memory location that it may have owned at some point but which had been freed and reused for a vector block, or for a new vectorlike within the existing vector block. There's a native comp unit in the block, and a lambda_gc_guard_h table. Can you p (struct Lisp_String *)0x000000001cfbfe40 to find out which one it is? Thanks, in any case, even though I'm kind of stumped right now...

Can this be due to a GCC optimization bug, whereby it truncates 64-bit values to 32 bits? Maybe George should try -fno-tree-sra?

Have you customized anything to 256 MB, precisely or approximately?
What are your values for gcmh-high-cons-threshold and
gcmh-low-cons-threshold, assuming that was in use during the crash?

Not that I could find, unfortunately. = My gcmh-low-cons-threshold is at 800000 and gcmh-high-cons-threshold is at = 134217728.

Thanks for checking! > (gdb) p (struct Lisp_String *)0x000000001cfbfe40 > $19 =3D (struct Lisp_String *) 0x1cfbfe40 Oh, sorry, "p *(struct Lisp_String *)0x000000001cfbfe40". I'm surprised 0xffdf6e1 is a valid pointer, and 0xffdf6e5 would be a Lisp_Object pointing to a two-element vector, which might be the lost constants vector. So maybe someone flipped a bit, or incorrectly treated the object as a fixnum and silently decremented it? Eli's idea of adding -fno-tree-sra to the build options for the next build is a good one.

I got another emacs crash, this time I was using 30.1 with both Pip's patch and the gcc flag -fno-tree-sra during compilation, although the crash is probably unrelated, as it is in redisplay instead of GC. The crash also coincided with my Windows computer (remember I am using Cygwin/X to ssh to a linux machine to open up an emacsclient) being forcefully restarted with a frame open. Unfortunately, I have no way of knowing with certainty that the crash happened during my Windows restart, as both took place overnight. I have included the backtrace below, it seems that displayed_buffer is not a valid address.

Hi!

I got another emacs cras= h, this time I was using 30.1 with both Pip's patch and the gcc flag -f= no-tree-sra during compilation, although the crash is probably unrelated, a= s it is in redisplay instead of GC. The crash also coincided with my Window= s computer (remember I am using Cygwin/X to ssh to a linux machine to open = up an emacsclient) being forcefully restarted with a frame open. Unfortunat= ely, I have no way of knowing with certainty that the crash happened during= my Windows restart, as both took place overnight.

I have included the backtrace below, it seems that displayed_buffer is not= a valid address.

According to this comment in window.h, that would mean it's a pseudo window, but another comment says the selected window is always a leaf window: /* For a leaf window or a tooltip window this is the buffer shown in the window; for a combination window this is the first of its child windows; for a pseudo window showing the menu bar or tool bar this is nil. It is a buffer for a minibuffer window as well. */ Lisp_Object contents; /* This is the window in which the terminal's cursor should be left when nothing is being done with it. This must always be a leaf window, and i= ts buffer is selected by the top level editing loop at the end of each comm= and. This value is always the same as FRAME_SELECTED_WINDOW (selected_frame).= */ So this looks like an inconsistent state reached by the redisplay machinery. We'd have to check whether it's the code above or actually this code: if (update_miniwindow_p) =09{ =09 Lisp_Object mini_window =3D FRAME_MINIBUF_WINDOW (sf); =09 displayed_buffer =3D XBUFFER (XWINDOW (mini_window)->contents); =09 internal_condition_case_1 (redisplay_window_1, mini_window, =09=09=09=09 list_of_error, =09=09=09=09 redisplay_window_error); =09} While it would probably would have avoided the crash to check whether XWINDOW (whichever)->contents is Qnil before setting displayed_buffer, I don't think that's the right fix: violating that internal redisplay assumption is a bad thing, and we need to figure out why it can happen when windows are being deleted (possibly in delete-window-internal?) Can you look up the line numbers against your source tree to see which code segment was active when the error happened? Thanks!
