, _retainCount = 0

, virtual .

. : (gcc 3.4.3)

#include<iostream>
using namespace std;

class A
{
    public:
        A(){cout<<"A ctor"<<endl;};
        virtual ~A(){cout<<"A dtor"<<endl;};
        void testDel()
        {
            delete this;
        }
};

class B: public A
{
    public:
        B(){cout<<"B ctor"<<endl;};
        ~B(){cout<<"B dtor"<<endl;};
};

int main()
{
    B bObj;

    bObj.testDel(); 
   return 0; 
}

A ctor
B ctor
B dtor
A dtor
