The trace-malloc code consists of the nsTraceMalloc code in [http://lxr.mozilla.org/mozilla/source/tools/trace-malloc/lib/ mozilla/tools/trace-malloc/lib/] and the perl scripts and trace-malloc readers in [http://lxr.mozilla.org/mozilla/source/tools/trace-malloc/ mozilla/tools/trace-malloc/]. It works by overriding / hooking into malloc and free (and related functions) and logging all calls, with stacks. It is probably the best tool we currently have for gathering aggregate memory usage statistics. It is generally more useful for bloat measurement than leak measurement, but it can be used to find leaks.

It is generally more useful for bloat measurement than leak measurement, but it can be used to find leaks. It works on Windows, Linux (x86), and Mac (PPC and Intel). It can be built by checking out mozilla/tools/trace-malloc/ and building with --enable-trace-malloc. | ||
'''Update''' (2003-06-16): There is a new trace-malloc tool, leaksoup, that is useful for finding leaks. See below for more information on how to use it. | '''Update''' (2003-06-16): There is a new trace-malloc tool, leaksoup, that is useful for finding leaks.
