The handling of the re-registration case is wrong here; the "test" that was returned from auth_domain_lookup will not be used again, so that reference should be put. And auth_domain_lookup never did anything with "new" in this case, so we should just clean it up ourself. Thanks to Akinobu Mita for bug report, analysis, and testing.
