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.
