Until you don't give us a working example, the above
code is meaningless, since anything can happen.

To the problem with not getting the SIGFPE in RHIDE.
Running under W95 and trying to reproduce a crash
is sometimes a pain. Simply running it under raw
DOS using cwsdpmi is much better to get a good crash.
