I'm not sure why I am getting the internal error below? I have sent it to the Mathworks support team, was just wondering if someone here might be able to see something or give me advice?

			i rewrote parts of my project, eliminating loops. 
It fixed it.
Those loops were running through multi dimensional cell arrays doing various tasks.
Since the problem occured infrequent i can not pin it directly to a single method.
But it has not shown up for weeks, one of those loops probably continued outside its address range. 
I would still love to read on how one can pin down the responsible line of code, starting with the error msg type above.
