How to track down the actual code that causes this memory leak, in Xcode?

I am having a dickens of a time trying to find the code that causes the memory leak you see in this image:

In Xcode, how to you go from this information in Instruments to finding the actual code? When I run Analyze, I do not get any warnings about memory leaks, but clearly something is leaking. I cannot double click on this logged line in Instruments to get to the line of code, there just doesn't seem to be anyway to track it down. I hope someone can provide the obvious solutio开发者_开发问答n that I am missing.
