It breaks in rcmd:
(gdb) r foo
Starting program: /usr/bin/rlogin foo

Program received signal SIGSEGV, Segmentation fault.
0x400e4910 in rcmd (ahost=0xbffff7cc, rport=258, locuser=0x804d6b0 "root", 
    remuser=0x804d6b0 "root", cmd=0xbffff7d4 "xterm/38400", fd2p=0x0)
    at rcmd.c:103
103             *ahost = hp->h_name;
(gdb) bt

	while (__gethostbyname_r (*ahost, &hostbuf, tmphstbuf, hstbuflen,
				  &hp, &herr) < 0)
__gethostbyname_r returned 0 and hp was set to null.
