Apologies for resurrecting an old thread, I am not sure it is entirely related.
I have not been able to use libGL on i386 for quite some time, the following
core dump might provide some information (the back trace is unusable/empty).
This is on current updated on 15 December. Unfortunately, I still do not know
the cause of the SIGSEGV.

Does glxgears work for anyone else (on i386+i915)?
