Good project. It finds actual bugs I care about fixing as well as bugs that are really just lazy programming habits. It's definitely worth running against your project to see what you find.
Too many false positives, hard to determine which is a real leak. I tried it with wxWidgets project - it does not seem to recognize that an object will be freed by its parent. I know that there is a way of listing those objects in a file, but its too tedious work to list all wxWidgets objects into a single file.
Just reflected on some reviews after compiling cppcheck with the latest mingw 4.8, as it builds from 25% to in my best case, 300% faster and more stable executables compared with "API drone msvc" There is some problems with the path interpreting procedures, mainly because the app have been under the bad influence of msvc conventions. The best remedy would be to use QT creator for all coding and abandon Visualstudio, and its portability corruption altogether Otherwise it's a promising project where some features work very good
