@Sergey : I currently do it, but it returns me a lot of leak, and a lot
looks like false positive...

Thanks Jean-Sébastien for AQTime ans gDebugger, I'll have a look at these.

Thibault, thanks a lot for this very detailed answer. I think I will find my
problems with all these possibilities.

Thanks a lot, I'll tell you if I find an easy solution to find memory leaks.
