This was reported in Ubuntu https://bugs.launchpad.net/bugs/87661 and I 
don't have the hardware to reproduce it, but I think this will be the 
same in Debian:

The ASM optimizations on mesa 64-bit builds include instructions (like 
for instance 3dnow) that are not available on Intel 64-bit processors, 
and hence some GL applications crash with SIGILL.

The proposed patch, in form of a Xsession.d script, sets the MESA_NO_ASM 
flag when 64-bit mesa is detected on a processor not having support for 
3dnow instructions.
