This is almost definitely a stack alignment issue. The ABI on Mac OS X
IA32 requires a vector aligned stack (16 bytes at function call
points). No other platforms require this, so HiPE probably doesn't
ensure it in the code it generates. EXC_BAD_INSTRUCTION happens when
you use an instruction that requires aligned operands but don't
provide them aligned.
