I don't understand how was this working without instantiating.
auto_ptr should have null pointer, when not initialized:
```explicit auto_ptr(_Ty *_Ptr = 0) _THROW0()
: _Myptr(_Ptr)
{	// construct from object pointer
}```

Normally without the auto_ptr debugger would give an error for freeing an invalid heap pointer.
