google-perftools is able to help analyze such problems.
It can produce memory reports in certain intervals of the program 
lifetime, and they graphically show who owns how much memory at 
particular times.

In a nutshell, the run is done like this:
HEAPPROFILE=google-profile-pid$$ LD_PRELOAD=/usr/lib/libtcmalloc.so $*
