AFAIU wikipedia, the most common problem with that processor are CMOV
instructions, which it cannot execute. However, the generic binaries
are not supposed to contain those instruction. If it still does (or
some other unsupported opcode), it might indicate a problem in the
toolchain. But as said, I'm curious to see the disassembly around the
faulting address.
