Memory leakage

// compile with: cl testMemLeak.cpp -D_DEBUG /MTd -Od -Zi -W3 /link -verbose:lib /debug
/
This program concentrates on allocating and freeing memory
* blocks to test the functionality of the _crtDbgFlag flag..
/
/
* The memory leakage info is output by OutputDebugString, which can be catched by DebugView

Modify xmemory
void deallocate(pointer _Ptr, size_type)
       {   // deallocate object at _Ptr, ignore size
       operator delete(_Ptr);
       }
to test memory leakage in STL
