Thanks for all your replies Chris, Jon and Ian!

I will implement a custom allocator and pass it to the unordered_map. But
for starters it looks like the Valgrind solution seems easiest. I am
working on Windows using Visual C++, compiler VC12. I will look for
Valgrind alternatives for Windows.

Thanks,
