Catching a Stack Overflow

My game keeps freezing ( I think an infinite loop ) at a certain point in time. However because no Stack Overflow Exception is shown its hard for me to handle the issue, and theres some doubt it is an infinite loop thats causing the problem.

Is there a way in unity to limit script execution time. For example, in Action script you can set it so that if a script executes for longer than x seconds, that it should stop the script. Is there a way to do this in Unity, or can someone suggest a way catch a potential infinite loop.
