undefined-behavior

Many bad things happened and continue to happen (or not, who knows, anything can happen) due to undefined behavior. I understand that this was introduced to leave some wiggle-room for compilers to optimize, and maybe also to make C++ easier to port to different platforms and architectures. However the problems caused by undefined behavior seem to be too large to be justified by these arguments. What are other arguments for undefined behavior? If there are none, why does undefined behavior still exist?

Is there any way to know if you program has undefined behavior in C++ (or even C), short of memorizing the entire spec?
