Visual Leak Detector 是一款专用于Visual C++的内存泄漏检测工具，它免费，开源，且鲁棒性高。
VLD很容易使用：
1. 安装完vld后，只要告诉Visual C++哪里去找到它的头文件和库。（下载地址：https://vld.codeplex.com）
2. 然后您只要在你的c/c++工程中加上下面这一行代码，就可以使用vld了：
#include <vld.h>
您的工程在Visual Studio debug模式下运行，运行结束后，Visual Leak Detector会将内存泄漏的报告打印出来。内存泄漏报告包含完整的调用堆栈，没释放的内存大小。双击其中的调用行，可以跳转到对应的代码行上。
这种方式能够高效得帮您快速诊断，修复内存泄漏问题。
CRT Debug库和VLD主要的不同之处在于：Visual Leak Detector 完整的展示了内存泄漏的调用堆栈。
下面就是一个VLD打印的内存泄漏报告例子:
