Hi Ryan,
  The new test crashes on chromium because self_address().address() is empty
(IPAddressToStringWithPort method crashes). Added a check to
call ToStringWithoutPort only when self_address().address() is not empty.

+                                         ? " empty address "
+                                         : self_address().ToStringWithoutPort())
                 << " to address " << peer_address().ToString();
     return false;
   }
