VS 2010中的内存泄漏检测问题 [英] problem for memory leak detection in VS 2010

问题描述

i定义uafxcwd.lib;项目设置中的LIBCMTD.lib，附加依赖性

我的项目是在VS2010中构建的。



现在我有找到内存泄漏的问题。因为通过添加此代码：

Hi,
i define uafxcwd.lib;LIBCMTD.lib in project settings, Additional dependency
my project is build in VS2010.

now i have problem to find memory leaks. because by adding this code:

#if defined(_DEBUG)
     #define _CRTDBG_MAP_ALLOC
     #include <stdlib.h>
     #include <crtdbg.h>
     #define DEBUG_NEW new( _NORMAL_BLOCK, __FILE__, __LINE__ )
     #define new DEBUG_NEW
#endif

我的项目将是错误：

my project will be errors:

void* __cdecl operator new(unsigned int .... already defined in ...
void* __cdecl operator delete(void*.... already defined in ...

推荐答案

请参阅我对该问题的评论。考虑使用其中一个内存调试器： http://en.wikipedia.org/wiki/Memory_debugger#List_of_memory_debugging_tools [ ^ ]。

Please see my comments to the question. Consider using one of the memory debuggers: http://en.wikipedia.org/wiki/Memory_debugger#List_of_memory_debugging_tools[^].

您添加的代码应该是：

The code you add should be:

#define _CRTDBG_MAP_ALLOC 
#include <stdlib.h>
#include <crtdbg.h>

#ifdef _DEBUG
   #ifndef DBG_NEW
      #define DBG_NEW new ( _NORMAL_BLOCK , __FILE__ , __LINE__ )
      #define new DBG_NEW
   #endif
#endif  // _DEBUG</crtdbg.h></stdlib.h>

仅在调试版本中有效。
