请教，利用VC检测内存泄露的问题

[lvguodong]

各位高手，我使用VC6.0做了一个控制台工程，里面包含C、C++两种语言，为了检测内存泄露，在一个总的头文件中添加了如下代码：

#ifdef _DEBUG
#define _CRTDBG_MAP_ALLOC
#include<stdlib.h>
#include<crtdbg.h>
#endif

在程序的退出点添加了如下代码：

#ifdef _DEBUG
_CrtDumpMemoryLeaks();
#endif

当我运行Debug模式并退出程序时，有如下输出：

。。。。。。。。。。

这个报告指明产生内存泄露问题的内存申请点是：（在crtdbg.h文件中）

#ifdef _CRTDBG_MAP_ALLOC

inline void* __cdecl operator new(unsigned int s)
{ return ::operator new(s, _NORMAL_BLOCK, __FILE__, __LINE__); }

#endif /* _CRTDBG_MAP_ALLOC */

我本来是要定位自己的源代码文件中产生内存泄露问题的内存申请点的，结果全指向了crtdbg.h中的这一条语句，这样我就不知道在哪一块申请的内存造成了内存泄露。

请教各位高手，我该如何解决这个问题，才能使我的内存泄露检测变得有意义？多谢了。
