iOS app crashes on ptr.get()

[mraiser]

After passing an AudioQueuePtr into AudioQueue.newInput, the iOS app crashes hard when I then call ptr.get(). There is no stack trace in the java console. I get the same error when attempting ptr.get() after passing an AudioFilePtr into AudioFile.createWithURL.

Thanks for the detailed bug report! I've looked into this and it seems like we have a bug in our bindings.

@BlueRiverInteractive: The AudioFile should not extend from CFType but rather be a NativeObject. It's defined like this in the AudioFile.h header:

typedef struct OpaqueAudioFileID    *AudioFileID;

So nothing that indicates that it's a CFType "subclass". Better look through other classes in that framework as well and make sure they don't extend from CFType unless needed.

I can confirm that the replacing the org.robovm.apple.audiotoolbox package with the one in the latest version of robovm-1.0.0-beta-01 fixes both crashes. Many, many thanks!
