Hmm, it seems to depend on the hardware you're using. I just tried it
on four different machines:
x86 (Pentium 4): SIGFPE
x86_64 (Xeon EM64T): SIGFPE
HPPA: "ERROR: integer out of range" (the intended behavior)
PPC (Mac OS X): no error, returns zero
So the overflow test in int4div is definitely broken and needs to be
changed. However, this is also a good question:

That still looks like a failure to trap something we should trap.
I'd suggest fixing that first, because if we fix int4div first,
we won't have a simple test case for it.
