  That is very strange.  It looks like the udpfromto code is being
handed invalid IP addresses when the server does DNS lookups.

  If you put an IP address instead of "*" in the listen section, does it
still do that?

  If so, I suspect that the issue is a socket initialization thing fixed
in 2.1.0.
