SubjectRe: VIA C3 and random SIGTRAP or segfault

Thanks, I'll check that out, though I'm a bit sceptical since the
crashes occur randomly not predictably, and that makes me feel it's
not because of an unimplemented instruction.

Also what about trace/breakpoint trap? Can that be also generated by
an illegal instruction?
