Visual Leak Detector 是一款專用於Visual C++的內存泄漏檢測工具，它免費，開源，且魯棒性高。
VLD很容易使用：
1. 安裝完vld后，只要告訴Visual C++哪里去找到它的頭文件和庫。（下載地址：https://vld.codeplex.com）
2. 然后您只要在你的c/c++工程中加上下面這一行代碼，就可以使用vld了：
#include <vld.h>
您的工程在Visual Studio debug模式下運行，運行結束后，Visual Leak Detector會將內存泄漏的報告打印出來。內存泄漏報告包含完整的調用堆棧，沒釋放的內存大小。雙擊其中的調用行，可以跳轉到對應的代碼行上。
這種方式能夠高效得幫您快速診斷，修復內存泄漏問題。
CRT Debug庫和VLD主要的不同之處在於：Visual Leak Detector 完整的展示了內存泄漏的調用堆棧。
下面就是一個VLD打印的內存泄漏報告例子:
