Strange debug error on XCode

Hi, I tried use new cocos2dx-2.2 from old cocos2d-x-2.1.0… I have a debug problem. When XCode stops in a breakpoints, the code debug is wrong… also the row wrong. The PC, skips a row or in few case jumps back and forth.
Any idea? I use XCode 5.0 (5A1413).

Thanks!

This happens to me too. It has since XCode 3 even. Also, XCode Version 5.0.1 (5A2034a) is out as well.

I find that doing a clean and deleting the DerivedData folder helps sync things back up.
