I don't mind saying that GCC should define cases that the language standards leave undefined. But that does not seem to be what this patch does. I don't see why this is a good idea. It seems to produce a program that is unpredictable in a different way. How does that help the user? If anything an infinite loop might be better, since it is more obvious that something is wrong. Unless I misunderstand. Ian
