I debugged the program completely and also tried it without the arrays. 
It must be a size problem. Maybe I am doing something wrong in using 
ulimit?? It seems to have no effect at all?? I will have another look at 
that. I will try the .bashrc option as mentioned by Dries Decock to try 
using ulimit, to see what is going wrong.
