I have tested this on Linux + DCO "client side" (which should not excercise this code path at all, so "no change") and have set up a server instance that has "--multihome" in the config - and as expected, the current code fails

Well spotted... (I do have a --multihome server instance somewhere, but not "with DCO", meh - now I have one).
