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;
}
