This needs know code in detail, it looks similir but I there is
following fragment that may mak these differ

 /* If we looked up IPv4 mapped address discard them here if
               the caller isn't interested in all address and we have
               found at least one IPv6 address.  */
            if (got_ipv6
                && (req->ai_flags & (AI_V4MAPPED|AI_ALL)) == AI_V4MAPPED
                && IN6_IS_ADDR_V4MAPPED (at2->addr))
              goto ignore;
