RoboVM app crashes on ptr.get()

问题

Is there some kind of magic required to get ptr.get() to work? For some reason the following code always crashes my app:

    AudioStreamBasicDescription asbd = new AudioStreamBasicDescription(mSampleRate, mFormatID, mFormatFlags, mBytesPerPacket, mFramesPerPacket, mBytesPerFrame, mChannelsPerFrame, mBitsPerChannel, 0);
    AudioFilePtr outAudioFile = new AudioFilePtr();
    File f = File.createTempFile("ptt", ".caf"); 
    AudioFileError afe = AudioFile.createWithURL(new NSURL(f), 1667327590, asbd, 1, outAudioFile);
    System.out.println(afe.name());
    System.out.println(outAudioFile.get());

It successfully returns from AudioFile.createWithURL with no errors (error code: No), but crashes as soon as I try to get the java instance. I'm also experiencing the same type of crash in another section of code where I instantiate an AudioQueuePtr as queueptr, pass it in to AudioQueue.newInput and try to call queueptr.get(). Is there something I'm missing here?

There's no stack trace in java, but here's the XCode Organizer Device Log:

Turns out this was a bug in the RoboVM bindings. Should be fixed in future releases. View the bug report here: https://github.com/robovm/robovm/issues/627

Also, I posted a full working example here: RoboVM implementation of recording demo using AudioQueue results in "No @Marshaler found" error
