This one happened on Windows while doing some other testing. This is probably going to be hard to track down.

The failure happened during a net/Broadcast test. Release version of the stdlib. Using release runtime.

pony_os_peername is only used in TCPConnection/remote_address.

Nothing in the TCP tests called remote_address and I hadn't modified them to call it.

backtrace:
