yes, I already seen this problem in my program !

I have found it is a problem with the debugger, and more precisally with 
the breakpoints. In my case I do a lot of conversions with atof for 
example, and when I put a breakpoint at a line the next line including 
this conversion will return NaN. I have tried to do the same things in a 
small project doing only the conversions but the problem didn't appeared !
I think the problem comes from a to big project, or a lack of security 
in the dynamic memory management !
