        When I run my App with xCode all loads and runs fine. When I load in Instruments and press record using a profiling template of Activity Monitor or Allocations it loads and runs fine. However if I use Zombies or Leaks the app crashes instantly. I dont even get to see it. I then access the crash logs in xcode and thought the reason for the crash is

        Exception Type:  EXC_BAD_ACCESS (SIGSEGV)
        

         

        Its almost impossible to debug as wach report is different.

        So I stop calling the line

        StoreManager.getProductIdentifiersFromServer()
        

         

        which stops the subsequent calls to

        JSONParser.jsonURL(_:jsonType:)
        

         

        Then the app crashes

        Does not seem to matter what functions I do or do not call I get a crash. It seems to me that its a system call and not one that I make thats causing the crash. Is it just me or is Instruments 9.3 crashing on Zombies and Or Leaks for anyone else?
