Random seg faults
i have no idea when it happens ( seems random from my point of few )
how it happens and i can't run a debugger, error.log only complains about missing sounds ( NFZ sound ?) and my client is dead. ( console says: seg fault ).
Had it happen about 3 times this weekend and there is basicly no way for me to get information out of the client, the setup its running on is gentoo linux ( with some security tools that might be the issue ).
if and dev can give me instructions who to create a proper bug report for this issue that would be great.
strace seems to freeze ( debugger trap ? ).
I stuff i run that might have a impact:
VSERVER+gentoo patched kernel 3.2 (i will submit my currently ugly ass kernel config if you need it ), initramfs is custom, full disk encryption ( luks ), apparmor, also, nvidia-glx ( last version as of last friday ), GNOME + Xorg.
Al of the software is build bleeding edge.
if there is some special trick to get VO in a debug mode i would be happen to figure out more details, as currently its almost impossible to debug the issue without the source code, it seems to happen more if i run a other application that is also using the audio. ( but this could be my illusion as i run VO more with applications using the sound output )
Hardware used:
Lenovo W520 + some extra memory and hdd's, I only have this issue with VO and all memory tests seem to think the memory is fine.

Out of curiosity, have you tried it with a not-bleeding-edge install? Like an nvidia-glx capable LiveCD or some such?
Does the bug reporter come up after the crash? If so, and you submit the bugs, we may be able to track it down from that.

for the forums i will post a detailed story when i get home(today/tomorrow) consider it resolved for now.
Full story:
As far as i could figure it out it seemed to happen mostly when running a other audio using application seems like there was a conflct with over alsa, when i recompiled alsa the issue went away.
