if a ptr to member function declaration differs from the prototype of the
actual function being used, and the function is implemented in a subclass, and
inherits from multiple base classes, the 4.x compiler generates a 0 for the
__delta which cause the appl to crash when the function is called through the
pointer with a wrong this ptr (pointing to the baseclass offset instead of the
objects).
problem was introduced with g++4.x, tested ok with g++3.4.

Summary: ptr to member func __delta is 0 if ptr declaration does
