I'm new to the concept so don't be hard on me. why doesn't this code produce a destructor call ? The names of the classes are self-explanatory. The SString will print a message in ~SString(). It only prints one destructor message.

int main(int argc, TCHAR* argv[])
{
smart_ptr<SString> smt(new SString("not lost"));
 new smart_ptr<SString>(new SString("but lost")); 
return 0;
}

Is this a memory leak? The impl. for smart_ptr is from here

//copy ctor
    smart_ptr(const smart_ptr<T>& ptrCopy) 
    {
        m_AutoPtr = new T(ptrCopy.get());
    }
    //overloading = operator
    smart_ptr<T>& operator=(smart_ptr<T>& ptrCopy) 
    {
        if(m_AutoPtr)
            delete m_AutoPtr;
        m_AutoPtr = new T(*ptrCopy.get());
        return *this;
    }
