Re: Where is my virtual function???

I've created the following class hierarchy in MS Visual Studio:

class B {
};

class D : public B {
public:
    virtual void g();
};

void D::g() {}

and created my object:
D* p = new D;

So far so good. I can see an "B" entry and __vfptr (const
D::'vftable') entry under 'p' entry in "Locals" window, and
I can see an [0x0] entry for function g() under __vfptr.

But if I add a virtual function f() in class B:
class B {
public:
    virtual void f();
};

void B::f() {}

class D : public B {
public:
    virtual void g();
    virtual void f();
};

void D::g() {}
void D::f() {}

then virtual function g() disappears from __vftbl. Moreover
- __vfptr entry has moved under the "B" entry in "Locals"
windows (it was under 'p' entry formerly).

So my question is where has my function g() got?? And why
__vfptr moves from 'p' to 'B' ?
