问题描述
我的C ++ 6.0应用程序中存在内存泄漏，尽管我使用"LeakDiag"和"LDGragher"来检测内存泄漏，但无法解决它的泄漏.但是我找不到此泄漏的原因，我也已通过使用以下代码转储了内存:
I''m having a memory leak in my C++ 6.0 application, and I can''t fix it leak although I''m using "LeakDiag" and "LDGragher" to detect memory leak. But I can''t found the reason of this leak, also I had dumped memory by using this code:
define CRTDBG_MAP_ALLOC
#include <stdlib.h>
#include <crtdbg.h>
_CrtDumpMemoryLeaks();
这给了我这个结果，我也无法捕捉到此泄漏的原因:
which gives me this result and also I can''t catch where is the reason of this leak:

抱歉，我知道这个问题很无聊，但确实需要您的帮助.
Sorry, I know that this issue is very boring but realy I need your help.
感谢您的努力.
我已经通过在每个.cpp文件的顶部添加此代码来解决了这个问题，这将我引到了内存泄漏的正确位置:
Thanks for your efforts.
i had solved the problem by adding this code in the top of each .cpp file, and that leaded me to the correct position on the memory leak:
#ifdef _DEBUG
#define new DEBUG_NEW
#endif
谢谢
Thanks,
