A memory debugger I use is called Fortify.  I requires that you re-compile
your software (although it doesn't necessarily require any changes to the
code).  It is free, and I got it from ftp://garbo.uwasa.fi/pc/c-lang.  It
was originally designed to work with DOS, but also works fine under Unix.

It does things such as overwrite newly malloced memory to be non-zero,
has buffers before and after malloced memory to test for overruns, checks
for frees of memory not malloced, and overwrites memory when freed so it
doesn't have 'almost' valid data if malloced again.  It can force random
failures of malloc to stress test your application.  It also has a C++
interface that work with new and delete (I haven't tested this myself).

Cheers, Andreas.
