Hi,


I received the following crash report. I'm not sure what to do with it. Is there any way I can figure out what caused this crash, where it came from in my app, or what I should do to fix it?

For what it's worth, the crash usually happens while my AVAudioPlayer node is in its dealloc method, but I'm not sure if they are releated. Here is the stack trace from that thread:

Did you drop it into XcodeOrganizer?
