Valgrind is a GPL-licensed system for debugging and profiling Linux programs. It uses dynamic binary instrumentation, so applications do not need to be modified, recompiled or relinked. Programs run under Valgrind with a slowdown factor ranging from 5 to 100, depending on the tool. It works with programs written in any language because it operates directly on program binaries, and it provides coverage of user-space code including system libraries. It can be used on programs without available source code.
