I've been bitten by the same problem, but your test case is bogus. You probably
don't have a CPU that supports SSE4.X, and should not be using the smmintrin.h
header but rather emmintrin.h or xmmintrin.h.

The real issue I'm not really sure what it is, but it's not an illegal
instruction, that's clear.

I'm raising the priority to critical because it breaks every desktop app,
basically. Xorg, gtk2, qt, pixman are affected by this issue.


priority:  -> critical
