Not that I know of. However, the first step is to add this regression
test for SIGFPE [-patches CCed]. Note that this will probably redline
windows on the buildfarm. Once this has been added and all
architechures are in compliance, we can deal with the integer overflow

Triggering a SIGFPE is a bit tricky. On my i386 system the integer
divide will do it, but the rest just return +inf. Given there are
systems that don't SIGFPE the integer divide, I hope one of the others
will trigger... For UNIX systems I've made it try kill() first, that
seems the most reliable.

Have a nice day,
