Subject: 24.1.50; Abort in Fadd_text_properties on Windows
Date: Sat, 05 May 2012 21:18:56 -0600

Emacs 24.1.50, bzr revno 108131 on Windows 7.

Emacs crashed with an w32_abort() in Fadd_text_properties() when 
capturing a task in org-mode.

I still have the session running and can provide further debugging.

Backtrace as follows:

What is 'object' in frame #2?

Also, please show the Lisp backtrace.

Sorry, I should have been more clear.  I meant this:

 (gdb) p object
 (gdb) xtype

If "xtype" says it's a symbol, follow immediately by "xsymbol" to see
which symbol it is.  Other Lisp data types have their respective xFOO
commands to do similar things.

Btw, is this an optimized build?  I didn't pay attention before, but I
see now that the C backtrace is entirely bogus: almost all frames
there are "at eval.c:175", which is obviously nonsense, since the
function names are different.  The place where abort was called,
claimed to be textprop.c:129, is also a lie, as nothing around that
line can ever call abort (unless I'm missing something).  I'm guessing
it actually aborted at line 1194:

      if (i == 0)
	abort ();

Not sure what that means, though.

And what versions of GCC and GDB did you use?

Any hope of you remembering what you did at that point?

No, it's a debug nightly build from my Jenkins server. However, last
night another build got kicked of and some files might haeve been
updated from bzr. The build failed since the executable was still
running. Possible that the source does not match the object code.

> And what versions of GCC and GDB did you use?

gcc 4.6.2. gdb 6.8, which I used by accident, but there is nothing I can 
do now.
gdb 7.3.1 is the usual version I use.

> Any hope of you remembering what you did at that point?

Sure. I was using C-C r to trigger org-capture and then entering a line
into an org-capture template when it crashed.

If this doesn't lead to anything, I can keep an eye open for another
occurrence.

So it's a buffer.  "xbuffer" will show more details (but I'm not sure
this is worth pursuing, until we establish where exactly does Emacs
abort and why).

Could it be that the abort was caused by compiling/linking
incompatible files?

I suggest upgrading to the latest v7.4 (available from MinGW).

Sounds like this is the way to go.  Start Emacs from GDB, while you
are at it, so that "pp" etc. works.

Thanks.

(gdb) p object
$8 = 283151365
(gdb) xtype
Lisp_Vectorlike
PVEC_BUFFER
(gdb) xbuffer
$9 = (struct buffer *) 0x10e08c00
(unsigned char *) 0x110305d8 "CAPTURE-refile.org"
(gdb)

That's the buffer that is created by org-capture and that I was working in.

No, the crash happened last night (before midnight), so it was the
previous night's build. The build process was restarted at midnight but
failed since the instance was still running with gdb attached.

Cool. Will do.

OK.

It's been ~ 300 days with no more information, so I am assuming this
crash report is no longer relevant. If it is, please reopen (or make a
new report).
