mapmalloc is a tool to help debug and profile dynamic memory allocation
in C and C++ program. It operates in batch mode (not interactive). You
run your application with the mapmalloc utility and a log is produced
showing every memory allocation operation. For each allocation, you
get the address allocated and the size requested. You also get the
complete backtrace (using only addresses). For each free operation
you get the address freed.

Using postmortem tool such as maplog, you can extract various informations:
leaks, allocation per source directory  and various statistics.
