No compile-time error, but a run-time error may occur if multiple
inheritance is used. There is basically nothing we can do in this

class A { char c; };

class B { char c; };

class C : public A, public B { char c; };

C * pC = new C; // Let's say pC == 0x8000

B * pB = pC; // pB == 0x8001

pick_of(pB) will return 0x8001. It is similar to a "delete pB" attempt.
