Profiling and Memory Checking Tools

This is a collection of tools for profiling and memory checking. It's mostly a summary of programs/libraries mentioned in the forums, notably in threads Advice on checking for memory leaks and dangling resources? and Other tools for Qt Development

Linux, Mac OS X

Valgrind is the tool of choice for analyzing a variety of issues on Linux and Mac OS X. It uses individual tools for specific analysis like profiling and memory checking. Qt Creator's Analyze mode integrates Valgrind, and provides both memory checking and profiling functionality from within the IDE. Valgrind needs to be installed for that to work. Valgrind is not available on Windows, but since memory issues are usually not platform dependent, analysis can be done on Linux or Mac OS X as well.
