Undefined behaviour is undefined only by the standard - an implementation may choose to handle undefined behaviour in some documented, specific fashion. Undefined behaviour exists to give implementations exactly this flexibility.

Or they can leave it undefined and not make any guarantees. I do not think that any compilers on any platform makes any guarantee on signed overflow.
