iOS crash log: how to make sense of it when the crashing thread has no app frame
Please see the crash log below.
The crashing thread 66 and the Last Exception backtrace has no TestApp frame.
Can I conclude that the crash was caused by code that was not written by me?
Note: the TestApp did not symbolicate even though I have the dsym and all, not sure why at this point, by since the thread 66 and the exception backtrace had no references to the TestApp code, I did not spend time on manual symbolication so far.
EDIT: I am using ARC.
EDIT2 : I am using JS in the code also, so this crash might come from there also. Not sure how would show up if that's the case.

The problem came from Google Analytics.
Updated from 3.0 to 3.0.2.
So it seems that the crash came from an outside library.
