使用Visual Leak Detector检测内存泄漏

安装Visual Leak Detector

前往官网下载并安装。

设置

附加包含目录添加C:\Program Files (x86)\Visual Leak Detector\include
附加库目录添加C:\Program Files (x86)\Visual Leak Detector\lib\Win64
附加依赖项添加vld.lib
将vld.ini中的ReportTo修改为both

测试

写一段内存泄漏的代码，然后运行，程序结束后将会在调试器和文件中生成内存泄漏报告，VLD_FORCE_ENABLE宏定义是为了Release版本也能生成报告。

#include "stdafx.h"
#define VLD_FORCE_ENABLE
#include <vld.h>


int _tmain(int argc, _TCHAR* argv[])
{
	VLDGlobalEnable();
	VLDReportLeaks();
	char *strTest=new char[1024];
	sprintf(strTest,"111111");
	printf(strTest);
	VLDGlobalDisable();
	return 0;
}

提醒

该工具只能检测堆(Heap)上分配的内存泄漏，不能检测VirtualAlloc(Private Data)申请的内存泄漏
