I did not say "I think". I actually tried the function and got the results. I
tried on different machine (XP, VISTA, WIN 7). I used exact same configuration.
But I got different results.

class Base
{
   virtual void func() {...}
};
class Derived : public Base
{
   virtual void func() {...}
};

Base b;
b.func();
Derived d;
d.func();

class Shape {
   bool state;
public:
   inline virtual void initialize() {
      state = false;
   }
   inline virtual ~Shape() {} // will always be resolved statically!
};

class Square : public Shape {
   float width;
public:
   virtual void initialize() {
      Shape::initialize(); // resolved statically - this can be inlined!
      width = 0.;
   }
   ~inline virtual ~Square() {} // may be resolved statically
};

int main() {
   Shape* pShape = new Square;
   pShape->initialize;
   delete pShape; // calls pShape->Shape::~Shape() and then pShape->Square::~Square()
                  // this can be resolved statically since the compiler at this point knows the type
   return 0;
}
