The same source code compiled with Linux/gcc can run when FOAM_SIGFPE is NOT set, but will crash in the same location when FOAM_SIGFPE is set in the env. So obviously, this is an issue with the Foam::sigFpe::set() implementation. Is there any special gcc switch used in the Linux compilation that allows more tolerance to division by zero? Any suggestions?
