Need to find out who is retaining an NSMutableArray
<p>I have an issue where I need to find out what objects are retaining a NSMutableArray. If it is an object I created I can just override retain and release and set a breakpoint on it, but since it is a NSMutableArray I can't. I tried to subclass NSMutableArray but I get exceptions when I try to add to my subclass. Any ideas?</p>

<p>I know you should not really be looking at retain counts but this is complicated code that I inherited and don't know what objects are retaining it. </p>
