output of dmesg| grep nouveau

The nouveau driver crashes somwhere while doing EXA stuff ( I can reproduce it
by opening the noscript menu in firefox or using thunderbird for some time..)
gdb gave me this output:

Program received signal SIGSEGV, Segmentation fault.

Is it still the case on recent version of xf86-video-nouveau?

--- Comment #4 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The altlinux bug is completely unrelated. That one happens when the GPU has
locked up, EXA doesn't handle that quite as gracefully as it might and so X
crashes. This was a much more, uh, "legitimate" crash, and not
provoked by a
heavily-using GL app. As we haven't heard from the original reporter in
almost
4 years, closing this as invalid (since "fixed" is a bit too strong).
