Recoding the malloc is a mess. It seems to be a very good exercise and it is. But you know there are so much mystical issues that happens when you're working with memory.

I just figured out that I got 90% of my free function calls by the "ls" command that was in reality a bad pointer following my own verifications.

So, I don't know why because I just make a normal vérification so except if the "ls" was developer with the ass...
