Cannot fail.

I commend to you a paper titled "Can't Happen, or /*NOTREACHED*/, or
Real Programs Dump Core", by Ian Darwin & Geoff Collyer. It can be
found in the proceedings of the Winter Usenix Conference, Dallas 1985,
pages 136-151. Or FTP to cs.toronto.edu will get you the Postscript
version under doc/programming/canthappen.PS.
Since "anything that can go wrong will go wrong", it is a programmer's
responsibility to deal with Murphy as gracefully as possible. Dumping
core is never graceful.
