Regular crashes with abort() in mark_maybe_pointer with trunk

Regular crashes with abort() in mark_maybe_pointer with trunk

Hi,

Since at least yesterday, latest trunk version crashes regularly.

I've grabbed 2 backtraces so far, attached.

I'm sure that the change responsible has been done between the commits:

commit 1e211d886c96420904ad197cfee7fce7ae7b9d83
Author: Stefan Monnier <monnier@iro.umontreal.ca>
Date:   Fri Jun 22 09:42:38 2012 -0400

    Provide generalized variables in core Elisp.


commit b17778189e1df0a56e48a5f6f0b52f7bebbdfdd7
Author: Julien Danjou <julien@danjou.info>
Date:   Thu Jun 28 12:40:24 2012 +0200

    term: rework color cutomizing


I know this because emacs-snapshot for Debian that I package worked
correctly for the 20120622 version, and stopped working with this last
commit. Something in between changed something causing this.

If nobody has an idea, I can try to bisect but that will require
sometimes since the crash is still random to me (not sure how to
reproduce for sure).

Both crashes says that mem_node tree is damaged :-(.

Can you try to reproduce crash with CFLAGS='-O0 -g3' and with
--enable-checking=all?  If you can grab the postmortem core, it
would be helpful if you put _both_ core file and emacs binary
somewhere on the net, so someone will be able to perform in-depth
analysis with gdb.

Here's one. I was not able to compile with --enable-checking=all (one of
the .el file seemed to take forever to compile, did not dig into this).
I don't have the core file, I launched emacs through gdb but I can
probably get one if that's better.

Hm, this crash is not in mark_maybe_pointer (but your previous two crash
reports was).  String compaction code is known to be quite stable.

If full bootstrap with '-O0' and --enable-checking=all is painfully slow
for you, try normal bootstrap and then just recompile with these options.
Thus you can avoid rebuilding .elc with the very slow Emacs instance.

Please describe your environment.  Are you sure that your compiler is not
buggy?

Final note: make sure that your hardware is not broken.  Random crashes
is a well-known symptom of bad RAM.

I tried with --enable-checking=all, but 12 hours later on my dual core
box it did not finished compiling all the .el. Not sure what this flag
does, but it's long. :)

Unfortunately, it seems that -O0 makes the bug go away. :-( By default
the Debian package specified -O2.

I'm running Debian unstable with gcc 4.7.1.

Nop, it's happening to other people running my package also. :(

Ahah. I pressed C-c C-c to send this mail and it crashed. I just had to
be patient.

Attached is the backtrace. I've both the binary and the core file is
needed, I can provide them to you privately.

Configure was:
./configure --build x86_64-linux-gnu --host x86_64-linux-gnu --prefix=/usr --sharedstatedir=/var/lib --libexe      cdir=/usr/lib --localstatedir=/var --infodir=/usr/share/info --mandir=/usr/share/man --with-pop=yes --enable-loca      llisppath=/etc/emacs-snapshot:/etc/emacs:/usr/local/share/emacs/24.1.50/site-lisp:/usr/local/share/emacs/site-lis      p:/usr/share/emacs/24.1.50/site-lisp:/usr/share/emacs/site-lisp --without-compress-info --with-crt-dir=/usr/lib/x      86_64-linux-gnu/ --with-x=yes --with-x-toolkit=gtk3 --with-imagemagick=yes 

Make was called with:
make -j2 CFLAGS="-DDEBIAN -DSITELOAD_PURESIZE_EXTRA=5000 -g3 -O0"

I've been seeing intermittent crashes and bootstrap failures (stack
traces always point to GC-related code) on the trunk for months now.
The failure comes and goes, seemingly at random, when unrelated changes
are committed.  Bisection has not been useful to me, perhaps because
the underlying problem is merely triggered by the presence of new code
inducing some sort of change in the bootstrapped temacs.

For example, between June 19 and some time in June 25-27, I failed
to bootstrap from the trunk because of this sort of problem.
However, since June 28th bootstrap succeeded.
Here are date/times of my recent successful trunk bootstraps:

  emacs-2012-06-01.07h20/
  emacs-2012-06-02.06h19/

I've finally spent time bisecting, and found what I think is the
culprit:

commit 172592b99f93e1bf03002a6769aa608e2776f44b
Author: Dmitry Antipov <dmantipov@yandex.ru>
Date:   Wed Jun 27 19:46:48 2012 +0400

    * alloc.c (allocate_string_data): Remove dead code.
    * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
    avoid GCC warning about unused macro.

I'm running with a recent trunk snapshot with this patch reverted, and
it seems to fix my problem so far.

Argh... it becomes obvious after your bisection. Fixed in 109122.
Thanks and sorry about such a stuff :-(.
