and there is also https://sourceware.org/bugzilla/show_bug.cgi?id=26601 which includes a test showing the same behavior as I obtain (only the IPv6 address with AF_UNSPEC, IPv4 address with AF_INET; due to a SERVFAIL). No nscd involved (but nscd might propagate the behavior without it, making it possibly worse).
