Where to even start. Firstly, the code you posted does not even demonstrate the point you're trying to make. The call in main() should be b->F() with no parameter. In g++ this correctly gives 10. With the parameter, it had better give 2 in Visual Studio like it does in g++, because that is what you are passing; you are not requesting the default.
