IOS7 - Xcode5 - Memory Leaks Without NO CODE

First of all, sorry for my English. Now I made a simple application in Xcode 5, it has a TabBar controller and a navigation bar controller built into it. When I launch an application with a profile, I see some leaks (32 bytes) that appear when the application goes into the background. This only happens when I use the built-in navigation controller in the table control panel, even if I don't write a single line of code. in the stack trace, the only function for leaks is in main.m.

How is this possible?

Leak Type:

Leaked Object   #   Address Size    Responsible Library Responsible Frame
__NSCFString    1   0x17530290  32 Bytes    Foundation  -[NSPlaceholderString initWithFormat:locale:arguments:]
