Need debugging version of malloc()/free()

[jkh]

I was thinking about writing this the other day, but figured I'd ask
around first before expending the effort.

Has anyone written a version of malloc/free that keeps extra information
around about each chunk allocated and free'd so that garbage things free'd
(or legitimate data free'd multiple times) can be detected and reported?

An additional plus would be for malloc() to somehow detect when you'd gone
off the end (either end) of a malloc'd block, but I can see how this would
be a lot harder to do, if not impossible in some cases.

Nonethess, I'm interested in anything that anyone's done in this dept.
