Project Description:

Visual Leak Detector is a free, robust, open-source memory leak detection system for Visual C++. It’s pretty easy to use. After installing it, you just need to tell Visual C++ where to find the included header and library file. Then it can be used with any C/C++ project simply by adding the following line to your code: #include <vld.h> When you run your program under the Visual Studio debugger, Visual Leak Detector will output a memory leak report at the end of your debugging session. The leak report includes the full call stack showing how any leaked memory blocks were allocated. Double-click on a line in the call stack to jump to that file and line in the editor window. It’s a very effective way to quickly diagnose, and fix, memory leaks in C/C++ applications.
