I'm getting the following error randomly (and sometimes consistently on launch). It can happen when there are background threads and when there aren't and it seems to be a problem with the library so I'm having trouble tracking down the problem in my code. The breakpoint triggers on:

#0  0x07bb489b in MP3AudioStream::GeneratePackets(AudioFileStreamContinuation&) ()

and the backtrace is as follows:

* thread #1: tid = 0x1c03, 0x07bb489b AudioToolbox`MP3AudioStream::GeneratePackets(AudioFileStreamContinuation&) + 2843, stop reason = EXC_BAD_ACCESS (code=2, address=0x4)

Has anyone had this error and does anyone know how I might go about fixing it?

  • Are you trying to play/download music when the app is in bg ? – danypata May 14 '13 at 21:35
  • I have it set up to do that, but I'm getting this error when the app is in the foreground and has not been backgrounded. – Kudit May 14 '13 at 22:18
  • I saw in other SO post that this crash log can be caused by the beginBackgroundTaskWithExpirationHandler, I don't know if is your case too but if it is you should check http://stackoverflow.com/a/5003199/2315974 – danypata May 15 '13 at 07:13
  • It isn't. I'm not using `beginBackgroundTaskWithExpirationHandler` anywhere in my code. – Kudit May 15 '13 at 14:15
