FYI: On ia32, the compositor crashes on an exception because of an SSE
instruction (movapd %xmm1,-0x298(%ebp)). If I am not mistaken, our FPU
context switch routines are SSE compatible, but we simply don't set the
specific bits in CR4 (OSFXSR, OSXMMEXCPT) to actually enable SSE. This
should be easy to fix.

Well, it was even more banal than that. The plain old stack alignment.


M.D.
