Memory leak in iOS Simulator?-Collection of common programming errors

I’m sorry if this is a dumb question but it’s possible to have a memory leak in the Simulator?

i was trying to figure why my app keeps crashing and the Instruments detected a memory leak will I was running my app. But now, I’ve started to record after open my app and I’ve a leak as well.

Here’s the image:

Is that normal? And how do I fix it?

UPDATE: I’ve closed the Xcode, open it without open any project, open Instruments and Simulator, record it and I’ve a memory leak without even touch the simulator. How is that possible?!
