@Jabo: you'll never be completely accurate that way. You'd have to account for padding in your structures, the sizes of any libraries you load (and of course, you'd have to do the calculations for those libraries too), etc... It would be a nightmare.

You can, however, find debuggers that will track memory usage and tell you how much was lost. For example, on Linux, Valgrind is one that does this. You run your program through it, and it will tell you how many blocks you lost and their size.

RAII is a common resource management idiom used in C++. Smart pointers (with and without reference counts) probably being the most common application.
