[Mesa-users] Mesa 7.11.2 Segmentation fault

[tom fogal]

Hi Eduard!

I recommend you do two things:

1) try this again with git's master instead of any 7.11 version.  That
branch was created back in summer and I think most developers think of
it as being in 'maintenance mode'; there are likely to be significant
changes at this point.

2) file a bug report (bugs.freedesktop.org).  I think this will get
lost otherwise.

It would be interesting if the valgrind output changed with/without
--disable-asm.  You might also want to make sure that GLX_USE_TLS is
defined.

Best,

-tom
