#91 Crash in nta due to a sresolv error event
A 1.12.7+ stack sometimes generates a crash when the network connection is brought down. An unregister request seems to have been sent before bringing down the connection, and the stack is most likely being shut down. Sorry, I can't reproduce it myself, and I have only talkback stack traces now, but I can try to get a better post-mortem if the cause proves unclear.
Notice the evident stack corruption in frame 5 and above.
