There seems to be some condition that causes a core dump in the current CVS
snapshot at line 598 of cbc-frame.c.

The backtrace is attached.

This is happening after trying repeatedly to attack the same network, and
mostly failing each time.  By mostly failing I mean that a zone transfer is
performed, the scan dialouge begins, then I get a core dump.  One time
nessus completed a scan of 4 hosts (out of about 30 that I see from a zone
transfer).

The 5 year plan:
In five years we'll make up another plan.
Or just re-use this one.
