In the file /usr/src/usr.sbin/httpd/src/main/util.c line 2048:
the p = gethostbyname(str) returns according to the man page:

     h_addr_list  A zero-terminated array of network addresses for the host.

                  Host addresses are returned in network byte order.

Maybe a check for (NULL != p -> h_addr_list) should 
be done before accessing the p->h_addr_list[0] ?
