In this tutorial, we will use Visual Studio Code. You can edit files manually but it’s much better to use some IDE. Instead it produces debugging information in DWARF format, which unfortunately, isn’t supported by Windows utilities.įortunately, Deleaker works on Windows and supports DWARF format. WinDBG doesn’t support DWARF format: as MinGW was born in Unix world, it doesn’t produce debugging information in PDB format, which is a de-facto standard on Windows. Suddenly, if you use MinGW you encounter the lack of tools to detect memory leaks.

That is why developers need a profiler, giving detailed information about allocated resources.

It is very easy to forget to release a GDI object and the application will freeze or crash unexpectedly. They can be very substantial as their limits are pretty low. Beginners may forget to use smart pointers instead of operator new / operator delete or possibly even don’t know that operator delete is required advanced developers may suddenly encounter circular dependency issues, or just abnormal memory usage.Īnother kinds of leaks is Windows specific: leaks of GDI, User objects, and handles. Why do you need a profiler?Įvery C++ developer faces some memory leaks sooner or later.

You can use MinGW from the command line, and in most C++ IDEs for Windows including Visual Studio, Visual Studio Code, Qt Creator, and CLion. It includes a compiler (GCC) and headers required to utilize WinAPI. MinGW is a popular open-source toolchain to build applications for Windows. In this article, we will show how to fix memory leaks in C++ if you use MinGW on Windows with the help of Deleaker, a memory profiler. How to find memory leaks in MinGW32 and MinGW64?
