[krbdev.mit.edu #5552] minor incompatability krb5-1.6.1 and OpenSSH_4.6p1, OpenSSL 0.9.8e

[brian@karoshi.ucsd.edu via RT]

FreeBSD-6.1-Release, OpenSSH_4.6p1, OpenSSL 0.9.8e, krb5-1.6.1, the
sshd daemon drops core during attempted password login.

This appears to be the result of a null 'opt' pointer being passed
to subroutine 'krb5int_gic_opt_to_opte' at line 235 in lib/krb5/krb/gic_opt.c

A workaround is to apply this patch:

diff -r krb5-1.6.1-dist/src/lib/krb5/krb/gic_opt.c krb5-1.6.1/src/lib/krb5/krb/gic_opt.c
234a235,236
>     if (!opt)
>       return 0;

which is arguably not the correct solution but allows me to continue work.
