Don't try building this just yet. At least on an i386, lots of things
If I'm following the code properly, the call to getanswer() on
gethostnamadr.c:655 is passing 0x1 into getanswer(), which in some
cases (e.g., mapping 127.0.0.1 to a hostname) is going to treat that
0x1 as a char *.
This causes anything that needs to map 127.0.0.1 to a hostname
telnet 127.0.0.1 will cause the local telnetd to coredump.
rsh 127.0.0.1 will cause the local rshd to coredump.
netstat -r will cause netstat to coredump.
(verified by rebuild libc with debugging: getanswer() is calling
strcasecmp() with 0x01 as an argument.) I have no idea what else
This seems a pretty obvious bug. Has anyone else seen it? If not,
maybe my source tree got corrupted, or something...
