-f option with kinit

Hi, all:

To begin with, we are using krb5 MIT implementation as Kerberos client.

My problem is, kinit crashes with the option -f.

1. Failure:
denalic01:/tmp/dlms/kerberos/apps <138> kinit -f [email]120117097110@SESSWIN2003.COM[/email] -M 070097105114049050051
Segmentation fault (core dumped)

2. Success:
denalic01:/tmp/dlms/kerberos/apps <140> kinit [email]120117097110@SESSWIN2003.COM[/email] -M 070097105114049050051
denalic01:/tmp/dlms/kerberos/apps <141>

It seems the command line is not quite right. Anything wrong with this -f option?

Looking forward to help,
Xu Qiang
