Thanks everyone, you are right. Putting \n means the printf fires, so the 
segmentation fault happens later.

Greatful if anyone is able to do a full debugging of this function. 
Basically it's a kind of queue finding waiting and turnaround times. I 
don't know exactly how it's working.

Compiler is G++, version 3.2.2, default options.

Thanks
