c++ 内存泄漏(memory leak)

环境：VS2013Update3

打印memory leak位置

Code Snippet
// compile with cl /D_DEBUG /MDd /EHsc leak2.cpp

#define _CRTDBG_MAP_ALLOC

#include <iostream>
#include <crtdbg.h>

#ifdef _DEBUG
#define DEBUG_NEW new(_NORMAL_BLOCK, __FILE__, __LINE__)
#define new DEBUG_NEW
#endif


int main()
{
    char *a = new char[10];
    char *b = (char*)malloc(20);
    _CrtDumpMemoryLeaks();
    return 0;
}

程序运行时，在memory leak位置block

BOOL Ccat8637_brandApp::InitInstance()
{
#ifdef _DEBUG
	//where detect memory leak,now will be break here!
	_CrtSetDbgFlag(_CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF);
	_CrtSetBreakAlloc(9554);
	_CrtSetBreakAlloc(9553);
	_CrtSetBreakAlloc(9552);
#endif
...ignore...
