Any suggestions on how to accomplish that?

I've tried using the Google "tcmalloc" library, but the results show the #1
heap-user is some function that can't be determined so I'm not sure how
helpful this information is.  In the case that it may be, I'm attaching the
output from "pprof --pdf --alloc_objects" for the Boost.Filesystem "finder"
program.

Google tcmalloc library:

TCMalloc Heap Profiler:

Some docs that might help interpreting the output:
