>Description:
tried to use the 16-bit NCSA Telnet for Windows bundled
with the K5 1.0 release to connect to my K5 server host
running the K5 telnetd (on a high port number as an
alternate). daemon gets through authentication okay,
then it calls startslave. when it gets to the fork
call, the daemon causes a hard crash (cold boot required).
i haven't stepped into the kernel yet, but it crashes
fast enough that gdb doesn't report the creation of a
new thread. it could be that the child starts, but dies
before the parent gets to return from the fork()
p.s. i can gssftp from aforementioned
host to itself without trouble. but self-telnet dies.
connecting with any vanilla telnet client causes the
same problem. any advice? anybody else had this problem?

see above. well, that's what happens to me.
