undefined behavior

Undefined behavior results when programs attempt to do things for which the standard defines no semantics, and requires no diagnostic either. Examples include dereferencing invalid pointers and dividing by zero. Executing such programs may cause them to produce incorrect results, crash, silently "work", or even format the hard drive.
It is commonly joked that undefined behavior allows the compiler to insert code that will start a game of nethack.
