Re: Address of two different objects of the same type

Hello everybody!

As far as I understand the C++ standard, pointers to two different
objects of the same type cannot appear at the same address. Now
please take a look at the following code:

#include <iostream>

struct A {};
struct B : public A { A a; };

int main()
{
   B b;
   A* p = &b;

   std::cout << p << std::endl;
   std::cout << &b.a << std::endl;

   return 0;
}

The output I am getting on Visual C++ 2005 Express Edition is:

0012F3D8
0012F3D8

Is this a bug? After all, we are dealing with two different objects
of the same type, so how can they appear at the same address?
