tools to determine memory leak in a c/c++ code [closed]

Answer 1

Although not a specialized tool for detecting memory leaks another option is the Boehm-Demers-Weiser garbage collector available from HP Labs.

It works as a replacement for new and malloc.

Here are instructions to use it as a leak detector. It is, or was, used by Mozilla as a leak detector for Firefox. If i recall correctly it was also used by Mono and DotGNU Portable.NET as a gc.
