From: Frank Terbeck <ft <at> bewatermyfriend.org> To: bug-gnu-emacs <at> gnu.org Subject: 27.0.50; Segmentation fault with --fg-daemon on Linux Date: Wed, 09 Oct 2019 03:55:23 +0200
I am running emacs in Linux. The base system is an up-to-date Debian
sid. Right now I am starting emacs via systemd and emacs' --fg-daemon
flag. I am mostly attaching GUI clients to this server instance. The
graphical user interface is a non-reparenting window manager (namely
xmonad). This build uses --with-x-toolkit=lucid --with-cairo as well as
--with-libsystemd.
The issue is emacs crashing, plainly. And I have not been able to iso-
late and specifics that are required for crashes to happen. I've seen
this sporadically with different builds of emacs from its master branch.
To look into it more closely, I rebuilt emacs with debugging symbols.
And luckily, I didn't have to wait very long. Emacs crashed within a
day.
I didn't so anything spectacular either. I think I was just switching
from a buffer to another. And emacs' uptime was pretty low too. Like an
hour or two, if I'd have to wager a guess.
Here is the stack-trace, as recorded by systemd's coredumpctl:

Looks like the crash was in Glib? It is strange that you see a problem that no one else sees, and you say you have had it for quite some time. Can you run Emacs under GDB? I hope it will show a better backtrace if you do so.

[Message part 1 (text/plain, inline)]
As a shot in the dark, does the attached patch fix things for you, or affect the symptoms? The idea is to prevent a reset hlinfo from looking like it's nonempty. (A fancier possibility would be to add one to end_row and end_col everywhere.)

This cannot be right, since zero is a valid column number.

And this cannot be right because of bidirectional editing support,
whereby beg_row CAN be greater than end_row.
The test whether mouse highlight info is valid should involve the
mouse_face_window and mouse_face_mouse_frame members., and if these
are valid, then the row and column numbers should be valid as well.
If the row or the column are invalid, e somehow failed to update them
when we computed the info and set the frame and the window members.

Took a while to trigger. Here is the backtrace. Unfortunately, it seems
I built emacs anew (which I do every now and then; this build is based
on 9a911b4af50) without passing --with-x-toolkit=lucid — meh. I'll add
that parameter again and rebuild and keep running from within gdb. Maybe
this will still be of use:

I guess we'll have to wait until next time. Seems like running in gdb makes the issue present itself less frequently. But maybe that's just a coincidence. Regards, Frank

Okay, new chance. :)
I've updated my laptop's emacs to master. This time, the crash doesn't
seem to be on exactly the same line as before, but a little earlier.
Still in ‘show_mouse_face()’, though.
Thread 1 "emacs-28.0.50" received signal SIGSEGV, Segmentation fault.

Okay, new chance. :)
I've updated my laptop's emacs to master, emacs-26.1-8984-g46fefb09745
in particular. I'm back to the build settings of the initial bug report:
./configure --prefix=/opt/emacs \
--with-x-toolkit=lucid \
--with-cairo \
--with-libsystemd \
CFLAGS='-ggdb3 -O0' \
LDFLAGS='-ggdb3'
This time, the crash doesn't seem to be on exactly the same line as be-
fore, but a little earlier. Still in ‘show_mouse_face()’, though:
Thread 1 "emacs-28.0.50" received signal SIGSEGV, Segmentation fault.

So hlinfo seems to be OK. What about this part:

^^^^^^^^^^^^^^^^^^^^^^^^

This window is dead, AFAICT, and its memory has been recycled. So
somehow we attempt to show mouse highlight on a deleted window or
something. I have no idea how this could have happened.
Moreover, the frame itself seems to have bogus values:

What exactly did you do immediately prior to the crash?

I was reading mail using Gnus. When I do, with an article visible, gnus
is configured to show three windows (Group left of Summary and Article,
with Article below Summary). Then I switched the visible workspace in my
X11 window manager to somewhere emacs wasn't visible, switched back to
the workspace with emacs and that's when I had then unresponsive emacs
window sitting there, with gdb letting me know about the segfault.
I can't tell for sure, if the crash occurred before switching workspaces
or if that's what triggered it — but I *think* switching workspaces was
involved in past crashes as well. But maybe that's another coincidence.
I did not close an emacs frame, though. I am not sure what I did in Gnus
last. Could be, that I was in this article-viewing layout I described
above and selected another article from the summary buffer. That causes
Gnus to reuse the current article window to display the newly selected
one. I don't know if internally that involves closing windows etc.
Sadly, my brand-new Thinkpad thought a hard lock-up over night would be
great fun. Of course this happens when I just triggered something hard
to trigger. Sigh. The gdb session is gone with it. :-(
Anyway. I'm running my emacs inside gdb again, in case it happens again.
Let me know if I can be of further assistance.

It sounds like switching workspaces is relevant to the issue at hand.
Can you try moving the mouse pointer off the Emacs frame before
switching to the workspace where Emacs isn't visible, and moving the
mouse pointer to a place where it won't be on any Emacs frame before
switching back? If you do that, do the crashes still happen?
Also, which window manager is the one you use?

Thanks. Next thing I'd like you to try is this simple band-aid:

If you do that, do the crashes still happen? I will try and remember this. The issue is, though, that because the problem occurs only as infrequently as it does, I can't guarantee that I will remember doing it every time, I switch workspaces. Because over the course of a couple of weeks, I switch workspaces hundreds of times easi- ly without anything ever going wrong. :) I usually have Emacs as a mostly full-screen window with small status bars above and below it. > Also, which window manager is the one you use? It's XMonad¹ — which is one of those tiling window managers that are not re-parenting window managers². ¹ https://xmonad.org ² https://en.wikipedia.org/wiki/Re-parenting_window_manager >> Anyway.

Do you want me to try this right away or give the "move the mouse pointer off of the window" routine a shot for a while first? Regards, Frank

Might as well try this right away, given that the success with moving out the mouse is not guaranteed.
