I'll help out: *http://tinyurl.com/dyz6t*

I've also had good luck with the Google "perftools" package (
http://goog-perftools.sourceforge.net/) for profiling code execution and
memory usage.  Their "TC Malloc" library can be used without re-compiling or
re-linking (via LD_PRELOAD on Linux).  It will dump a profile of heap usage
for every 1 GiB allocated and/or every 100 MiB of heap in-use.  These
parameters can be tuned programattically or by re-compiling their library.
