Memory Leak? Or bug in instruments?

I'm sure it's a memory leak, and I'm certainly no expert in memory allo开发者_StackOverflow中文版cation, but instruments says I have a memory leak of zero bytes...

Can someone explain what exactly that means?

The leaked object (including the responsible party that initiates it) should appear in the lower half part of the Instruments window, once you have selected the "Leaks Discovered".

Doing an "Analyze" (Command + I) in XCode will also show possible memory leaks in your code.
