I am not sure where it should be picked up from. How would I figure that out?

The library is from the same build as the rest of the Mesa binaries and the
library has debugging symbols available.

Comment # 3 on bug 94512 from 
This segfault is not restricted to starting X, but also happen with glxgears
and glxinfo in a multilib environment.


I also figured out those segfaults only happen if glx-tls is enabled. If
glx-tls is disabled X, glxinfo and glxgears work fine again.
