Crash mostly on 5S


#1

We are getting multiple crashes but as the stack trace does not show direct calls from our code it is hard to track down the cause. Any idea what could be causing this problem with the following stack trace?

Hi mtuff,

This looks like an issue we are currently investigating involving AirPlay.

There is a similar blog post that explains this issue in greater detail found here:
http://www.shinobicontrols.com/forum/shinobicontrols/2013/12/ipad-air-crashes,-ipad3-works-ok-gt-on-ios7

Let me know if you have any questions.

Kind Regards,
Andrew Polkinghorn
