Did one of the newer C++ standards declare that a non-virtual method call to a NULL receiver is undefined behavior?
As I understand it, it has never been legal, since calling the method requires dereferencing a NULL pointer. From ISO/IEC 14882:2003(E)), paragraph 5.2.5/3: “If E1 has the type 'pointer to class X,' then the _expression_ E1->E2 is converted to the equivalent form (*(E1)).E2”
