Description of problem:
While rebuilding gcc-4.0.0-12, I get the following in /var/log/messages:

Version-Release number of selected component (if applicable):
gcc-4.0.0-12
kernel-2.6.11-1.1381_FC5
kernel-2.6.11-1.1240_FC4

How reproducible:
Everytime, try to rebuild gcc.

Additional info:
I don't know, whether this bug is gcc or kernel, please reassign, if it's wrong 
- I still guess, it's gcc.
Comment 1 Jakub Jelinek 2005-06-17 22:47:31 UTC 
How could possibly a kernel crash be application's bug (unless the kernel
is miscompiled by gcc, then it could be a GCC bug, but from your description
I understand you are just building GCC and the kernel crashes while doing that).
Comment 2 Dave Jones 2005-09-26 18:22:25 UTC 
has this reoccured with any later kernels ?
Comment 3 Robert Scheck 2005-10-01 11:49:28 UTC 
Yes, using 2.6.13-1.1527_FC5 for rebuilding of gcc-4.0.2-1 for example:

I also get this result even with a newer kernel, just try it yourself - it is 
very easy to reproduce ;-)
Comment 4 Dave Jones 2005-10-02 23:38:29 UTC 
1527 is pretty old (Its based on 2.6.13, whereas current rawhide is at
2.6.14rc3git1). Can you double check with the latest kernel please ?

It looks selinux related, so I'll reassign to JamesM for the timebeing.
Comment 5 Robert Scheck 2005-11-11 15:25:08 UTC 
Same with 2.6.14-1.1633_FC5 (was a CVS checkout short after -1.1632_FC5) while 
rebuilding gcc-4.0.2-4 last night. Oh and if you maybe thing about something 
SELinux related, I can provide the following information: Latest SELinux 
targeted policy enforced - from Rawhide, no avc denied messages in syslog:

Comment 6 Dave Jones 2006-02-03 20:41:12 UTC 
I'm chasing a number of other slab related problems right now in the current
2.6.15-1.xxx kernels, which may be related to this.
Have you had any more recent traces ?
(The latest builds >= 1.1898 have some extra slab debugging turned on)
Comment 7 Robert Scheck 2006-04-02 16:14:35 UTC 
I rebuilt gcc 4.1.0-4 on a kernel 2.6.16-1.2068_FC6, which wrote me the

I'll reassign this to a devel/ bug, as it's likely to get fixed there first, and
then backported.

It's possible to cause this Slab corruption (?) also when rebuilding binutils.

Comment 16 Dave Russell 2006-09-25 15:28:20 UTC 
I now have two machines that suffer from this problem, newest addition to the
family is running FC6-T3

Currently affected kernel 2.6.17-1.2647.fc6

Machine does this on *every* boot, only way to get machine up and running is to
boot to single user mode, and then init 5 from there.

I've seen it,
There's so much we
Don't understand,

All what we can see!

Adapted and translated from Nena; thanks to all people solving this annoying
bug after about 15 months... :)
Comment 19 Dave Jones 2006-10-29 06:30:42 UTC 
None of the existing kernels have slab debug enabled, so that's the reason it
won't show up.  However, if this is still present, it'll now manifest itself as
a lockup, or other random crash.

I'm going to investigate producing -debug kernels soon, which may show that this
still exists.  There have been some recent fixes in the tty layer (where it's
believed this bug lives) upstream, but nothing definitive to prove that this bug
has actually been fixed.

Closing it may be premature, time will tell.
Comment 20 Robert Scheck 2006-10-29 12:38:31 UTC 
Hrm...
Comment 21 Dave Jones 2007-04-30 19:00:47 UTC 
hasn't been seen in a long time. I think this got fixed in one of the several
rounds of fixes that went into the tty code.
