MemProf is a tool for profiling memory usage and finding memory leaks. Its two major features are:

- It can generate a profile of which functions in your program have allocated memory, and how much was allocated by each function and by the functions it calls.

- It can scan memory and find memory blocks that you've allocated but are no longer referenced anywhere.

MemProf works by pre-loading a library to override the C library's memory allocation functions and does not require you to recompile your program.

One advantage MemProf has over some other similar tools that are available is that it has a nice GUI frontend and is relatively easy to use.
