Undefined behavior arises from valid code constructs for which the C++ 
language definition does not impose any requirements. That doesn't 
depend in any way on the compiler that you're using or on the target 
platform.

The *consequences* of using code whose behavior is undefined depend on 
the compiler and the platform.
