Exception while stepping in debugger

When I launch my application into the debugger it runs fine, but if I set a break point and step through code I occasionally get a malloc error (see below). It doesn't seem to be tied to a particular location in the code. It seems to happen when I step out of a function. Difficult to reproduce. I've tried launching my application using MallocDebug too, but it runs fine there too. Any clues? Could this be a problem with XCode, or is it a subtle problem in my code?


*** malloc[5142]: Deallocation of a pointer not malloced: 0x412f684; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug
