Hmm.. I don't have any machines that don't have a FPU..
However, in trap.c, if there was no math emulator loaded, I'd have
expected a SIGFPE, not a SIGBUS:
if (!pmath_emulate) {
i = SIGFPE;
ucode = FPE_FPU_NP_TRAP;
break;
}
Just to satisfy my curiosity, I'd like somebody to try this:

And make sure that it's actually being initialized...
