Hi,

I'd like to make a custom deleter resetting pointer to 0 or other value
(e.g. for debugging purposes) after resource has been deallocated.
Would anyone suggest better option to this presented below?

struct DeleterT
{
     void operator()(::T* ptr)
     {
         ::DestroyT(ptr);

         // uses Visual C++ specific integer type
         *reinterpret_cast<__int64*>(&ptr) = 0;
     }
};

Best regards,
