FIXME: On x86 at least, dividing the smallest representable integer by -1 causes a SIFGPE (division overflow). We treat this case here (to avoid a SIGFPE crash at python level), but a good solution would be to treat integer division problems separately from FPU exceptions (i.e. a different approach than npy_set_floatstatus_divbyzero()).

divide by zero should yield a complex inf or nan
