That's not true. Check out this snippit from v3-5-test inside open_udp_socket().

1383         res = socket(ss.ss_family, SOCK_DGRAM, 0);
1384         if (res == -1) {
1385                 return -1;
1386         }
1387 
1388 #if defined(HAVE_IPV6)
1389         if (ss.ss_family == AF_INET6) {
1390                 struct sockaddr_in6 *psa6;
1391                 psa6 = (struct sockaddr_in6 *)&ss;
1392                 psa6->sin6_port = htons(port);
1393                 if (psa6->sin6_scope_id == 0
1394                                 && IN6_IS_ADDR_LINKLOCAL(&psa6->sin6_addr)) {
1395                         setup_linklocal_scope_id(
1396                                 (struct sockaddr *)&ss);
1397                 }
1398         }
1399 #endif

Also note that interpret_addr() is a specifically IPv4-only function,
only used in the IPv4-only code inside nmbd (NetBIOS-only code).

AFAIK all of 3.5.8 is completely IPv6 enabled and working.

Please open a bug against 3.5.8 at bugzilla.samba.org and attach
level 10 logs there.

Thanks !
