Certainly.

(gdb) run
Starting program: /usr/local/bin/telnet -ax host

Escape character is '^]'.
[ Trying mutual KERBEROS5 ... ]

Program received signal SIGABRT, Aborted.

(gdb) bt

So, it thinks the ticket is DES-CBC-CRC and Heimdal doesn't support this,
alas the abort()?  Thats interesting when you also consider the fact that
remote host A runs MIT's krb5 and remote host B runs Heimdal though telnet
abort()'s when trying to connect to both hosts.
