If you're wondering why X's destructor isn't run, you need to make B's destructor virtual:
Yes, I know. I was not wondering about why the X's destructor is not run when deleting b, but why the X's destructor is called when deleting ptr. int main () { shared_ptr<B>* ptr=0; { shared_ptr<X> ptrX1(new X()); ptr = new shared_ptr<B>(ptrX1); } std::cout << "BEFORE" << std::endl; delete ptr; std::cout << "AFTER" << std::endl; B* b = new X(); std::cout << "BEFORE" << std::endl; delete b; std::cout << "AFTER" << std::endl; return 0; }
