 It is relatively difficult to demonstrate this defect in well-defined
-code.  It is possible to convert a member pointer to a member pointer in
-a derived class and then cast it back it to a different base class; if the
-second base class is stored after the first, the resulting offset will be
-negative.  However, this cast has undefined behavior because the member is
-no longer a member of a base or derived class of the member pointer's
-class.  To demonstrate the defect, either an empty base class or an empty
