Recently I had this issue with AsyncUDPSocket and I believe it's because AsyncUDPSocket is not thread safe, and in debug mode you may be running only a single thread while in distribution, various optimizations will cause it to crash.

I've converted over to GDCAsyncUdpSocket and my distribution builds do not crash. Good luck!
