[Swift-user] ignore exceptions?

Neil, one solution is to wrap your fortran executable in a shell app that catches the SIGSEGV and/or other signals that the program may be generating, and exits with a 0 return code.

Something like:

trap "{ exit 0; }" EXIT SEGILL SIGTRAP SIGABRT SIGSEGV # etc - whatever applies
