OpenGL applications segfault on startup

[Benny Siegert <bsiegert%gmail.com@localhost>]

Hi!

I have a problem on my Pinebook Pro (9.99.84 kernel and 9.2 userland, 
native X). 
Whenever I start an application that uses OpenGL, it immediately segfaults 
on startup. The simplest case is with glxgears:

meguro$ gdb /usr/X11R7/bin/glxgears
GNU gdb (GDB) 8.3
[...]
(gdb) run
Starting program: /usr/X11R7/bin/glxgears

Any ideas what this is? The backtrace suggests a Mesa issue, but what can 
I do in this case? Anyone else seeing this?
