The point here is that under Windows int4div s

This seems completely pointless. The question is not about whether the
SIGFPE catcher works when fired, it's about what conditions trigger it.
Is anyone working on this?

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
