>Description:
The isakmpd port experiences a SEGV due to a Null pointer
reference. This happens quite frequently when talking to
the native Windows 2000 IPsec client. A stack trace:
Core was generated by `isakmpd'.
Program terminated with signal 11, Segmentation fault.

>How-To-Repeat:
Set up a security association with a W2K box. FWIW, this was with
