如果是开发商业用程序，还是直接先向Rational公司索取试用版，如果觉得好，再购买正版。毕竟版权的问题嘛。不过Rational现在越来越黑，Rose2000每年都要索取技术支持费，想必Purify也是如此吧。上次拿到Purify的最新试用版在安装结束后都要输入LicenseKey实在是……

# Visual Leak Detector [](https://ci.appveyor.com/project/KindDragon/vld/branch/master) 
## Introduction
Visual C++ provides built-in memory leak detection, but its capabilities are minimal at best. This memory leak detector was created as a free alternative to the built-in memory leak detector provided with Visual C++. Here are some of Visual Leak Detector's features, none of which exist in the built-in detector:
* Provides a complete stack trace for each leaked block, including source file and line number information when available.
* Detects most, if not all, types of in-process memory leaks including COM-based leaks, and pure Win32 heap-based leaks.
* Selected modules (DLLs or even the main EXE) can be excluded from leak detection.
* Provides complete data dumps (in hex and ASCII) of leaked blocks.
* Customizable memory leak report: can be saved to a file or sent to the debugger and can include a variable level of detail.
Other after-market leak detectors for Visual C++ are already available. But most of the really popular ones, like Purify and BoundsChecker, are very expensive. A few free alternatives exist, but they're often too intrusive, restrictive, or unreliable. Visual Leak Detector is currently the only freely available memory leak detector for Visual C++ that provides all of the above professional-level features packaged neatly in an easy-to-use library.
Visual Leak Detector is [licensed][3] free of charge as a service to the Windows developer community. If you find it to be useful and would like to just say "Thanks!", or you think it stinks and would like to say "This thing sucks!", please feel free to [drop us a note][1]. Or, if you'd prefer, you can [contribute a small donation][2]. Both are very appreciated.
