Get Brian's patch from #5825 and his log message:
Fix a failure in binding the initiating side of a connection
on MacOS. MacOS doesn't like passing the size of the storage
structure (sockaddr_storage) instead of the expected size of
the structure (sockaddr_in or sockaddr_in6), which was causing
bind() failures. This patch simply changes the structure size
to the expected size.
Add a more clear error message in debug mode.
