your gdb is obviously useless ... did you actually build it with debugging and such ? most likely a bug in glibc/kernel i would guess
(In reply to comment #3) > your gdb is obviously useless ... did you actually build it with debugging and > such ? Oops, must have forgot to turn off optimisation. > most likely a bug in glibc/kernel i would guess Yes.
gmsoft tried with different kernels and found that 2.6.19 did not have the problem but 2.6.20 did.
Still working on this. The patch causing this issue is most likely this one : http://git.kernel.org/?p=linux/kernel/git/kyle/parisc-2.6.git;a=commitdiff;h=4650f0a5832033c78690811aa9b171764c11fc0f
After lots of testing, I've found out the guilty patch : http://git.kernel.org/?p=linux/kernel/git/kyle/parisc-2.6.git;a=commitdiff;h=2b163b71e6d4471cae74037cb680e885eafc8d64
Created attachment 145859 [details, diff] Patch the fixes the problem The attached patch fix the problem.
Kernel team, please include attached patch in next gentoo-sources.
(In reply to comment #8) > Created an attachment (id=145859) [edit] > Patch the fixes the problem > > The attached patch fix the problem. I applied the patch to 2.6.24-r3 but it didn't fix the problem, sadly.
(assuming it fixes a problem) Where has the patch come from? Who created it? Has it been submitted upstream? It's not in Linus' tree, which is generally our requirement for including patches.
Patch was applied upstream. Attaching new patch.
Created attachment 146641 [details, diff] fix signal trampoline cache flushing
The new patch does fix the problem.
Keeping an eye on this patch to see when it to hits Linus' mainline development kernel tree.
Hi, I have a similar problem as well with cp. cp segfaults during openoffice 2.4.0 emerge (during unpack).

It could be an other glibc glitch too. They are the only segmentation faults I get.
(In reply to comment #17) Great, I found what was wrong, the flag xattr. If coreutils ebuild is compiled with that flag cp will crash every time it is called from openoffice ebuild. Indeed, without that flag everything works great. Now it would be interesting to know why that append and how it interferes with glibc. Obviously, python script's segmentation fault has nothing to do with that flag.

It's probably best to open a new bug report for this, if it is indeed a bug.
The patch is in vanilla-sources-2.6.25 and therefore in gentoo-sources-2.6.25-r1 as well.
