Haven't got the time to investigate it yet, though.I think this is because the stats structure is not initialized at startup and therefore contains random data. On the 6203 variables are not initialized to zero automatically! (There is a compiler/linker option to enable this, but for some reason I don't remember right now using it wasn't a good idea ..)
In my case this wasn't the problem. I had reasonable values, then after a while, it got all funky.. (very large number of allocated blocks, jumping randomly, etc., and the stack didn't work very well then either :) But since it was when I was using an experimental branch of my project, I haven't looked into it yet..
