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..
