Ouch!

How come values are "optimized out" when you compiled without
optimizations?  Can you show a sample GCC compilation command line
from the build process, with all its switches?

Also, please type "source /path/to/src/.gdbinit" at GDB's prompt
(where "/path/to/src/" is the Emacs src directory), and then type
"xbacktrace", to show the Lisp-level backtrace.

Thanks.

Do the crashes go away if you compile without optimizations?

No, sorry.
It could be possible, but my system will be maybe unstable if i do that.
The 4.5.1-r1 version of gcc is still unstable and i don't want to switch
to it yet.Thus it is a major version switch (4.4==>4.5) and it's always
tricky to change, even more to switch back to the stable version (a lot
of packages to recompile, etc..).

What about switching to a newer GCC (4.5.x)?  Is that possible for
you?

I have tried to bissect like this without success.
The main reason is i think the bug is not directly related to Emacs but
to the version of gcc (4.4.4) you use to compile emacs and/or maybe the gtk+
version (2.22.1) that is used on this system (just a guess).
See related post of Juanma about gcc.
As i said in precedents post, it's out of question i switch back to an
other version of gcc (3-*).

Since you are the only person who has been experiencing this crash,
please make an effort to bisect and find the bug.  Otherwise, the

From your previous message, the bug started at least on Sep 21, so I
would revert to a copy from July and see if the bug happens.

Sorry for late reply here, i just forget.


,----[ system-configuration ]
| "i686-pc-linux-gnu"
`----

,----[ system-configuration-options ]

So actually before crashing with segfault, i crash immediately when i
launch gnus with:

,----
| Program received signal SIGABRT, Aborted.
| 0xffffe424 in __kernel_vsyscall ()
`----

NOTE that Emacs23 development branch work fine here without crashing.

I really don't know, i have to check the doc.
Maybe i am wrong and what you use in command line is the same as
CFLAGS="-O3 -march=i686 -pipe"
        ^^^
in make.conf and not
MAKEOPTS="-j3"

Yes sure, no dependencies needed, just load and use 
M-x traverse-deep-rfind
on a big but reasonable directory (it is not rgrep, it's slow).
The test i do take 172s here when it success.
Use a regexp for "only" e.g .*\.el$ or nothing to stress more emacs.

But i think using anything else to generate a lot of activity in Emacs
should do the same. e.g using many tools at the same time.

A good point is i couldn't crash Emacs23.2 at this game :-)

;;
;; Usage:
;; =3D=3D=3D=3D=3D
;;
;; M-x `traverse-deep-rfind'
;; That is the interactive recursive function of traverse.
;; It will search for a regexp in all files of a directory
;; tree and his subdirectories.
;;
;; When searching is done and you are in traverse buffer
;; some interactive actions are provided for navigate
;; Use "C-h m" for more info while in traverse-buffer.
;;
;; You can also use traverse from DIRED:
;; M-x `traverse-dired-search-regexp-in-anything-at-point'
;;
;; This function work on directory, files, (1)compressed files (AVFS)
;; and marked files:
;;
;; If you have marked files search will be performed only on these files.
;; (No recursion will be performed on marked directories, so don't mark dir=
ectories.)
;;
;; If no files are marked, traverse will search in element at point
;; with appropriate function.
;;
;; However, you can use specialized functions, check this file to see all
;; the interactives functions.
;;
;; M-x `traverse-dired-find-in-all-files'
;; Search in all regular files in the current dired buffer (no recursion).
;;
;; M-x `traverse-dired-browse-archive'
;; This function use (1)AVFS to browse archive tar.gz, bz2 etc..
;;
;; (1)NOTE: You have to install AVFS and enable fuse in your kernel if
;; you want to browse and search in archives.
;; Please see the doc of your DISTRIB and the doc of AVFS here:
;; http://sourceforge.net/projects/avf
;;
;; If you want to use AVFS in traverse, set `traverse-use-avfs' to non--nil.
;;
;; Traverse provide also diverses functions to use in your programs.
;; (especially for recursion like `traverse-walk-directory'.)

Ah! ok, i use -j3 in my make.conf according to gentoo recommendations
for my processor i686 Genuine Intel(R) CPU T2130 @ 1.86GHz GenuineIntel.

So from another build of emacs

i crash with again this error in alloc.c:

I can crash at everytime now using the same command that recurse
through a big tree and match regexp in file (like rgrep but all lisp).

This same command work fine in 23.2 (on same conditions of course).

But as i said in precedent posts, i can crash also doing simple things
e.g next-line in any buffer.

A couple of questions:

- Are you using GCC 4.4.0 or later?
- Does the crash happen both with optimized and non-optimized builds?

I ask because I've been getting garbage collection crashes for a while
with non-optimized builds built with GCC 4.4.0, 4.5.0, 4.5.1, etc. The
problem disappears if I revert back to GCC 3.4.5 or build with
optimizations.

Yes, i will try first to find a day, i am actually on last commit of 20
sept, if it crash i will go on last commit of 19 and so on.
Once i find the good commit it should be easy to track all commits of
one day, maybe with git-bisect between good and last bad.

Thanks.  Crashes in GC are hard to track down (etc/DEBUG has some
guidance, but it needs some proficiency to actually follow through).
Knowing which commit caused the problem makes it much easier to find
the culprit.

It work fine a long time but finish by crashing also just moving down

But with better debug infos, i hope this will help you:

Ah! ok, i don't have this plugin and don't know how to install it.

Yes

It will be difficult because i don't build emacs myself actually, i use
the gentoo package of Emacs-vcs.

However, i will build an emacs from git tomorrow and try to downgrade
until i find a working version.

It could be long though as the crash appear at anytime, not necessarily
on costly operations.

system-configuration and system-configuration-options are Lisp

Sorry, I forgot to mention that you will need to install the bisect
plugin, if you don't have it already.

So it is crashing on your system for the last week or so, is that
right?  Is it possible for you to find the last version which did not
crash (or the first one that did)?  "bzr bisect" makes this easier,
but you could do this by hand as well, using "bzr revert -r".

TIA
