You are caught in quite a tangled web. The hardware gets a floating point trap, Linux/BSD/OS X turns it into a SIGFPE, vx32 turns it back into a hardware trap, Plan 9 turns it into a note, APE turns it back into a SIGFPE. Unfortunately for you, vx32 does not do a very good job turning SIGFPEs into the correct hardware trap. Someone needs to go through the various systems and figure out what the right mapping is from info->si_code back to x86 exception code. When I started to do this, I got very confused and didn't care enough to muddle through. Russ
