--- Comment #3 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> ---
To reproduce, one needs these two rules:

no rdr inet proto tcp from <white> to any port smtp
rdr pass inet proto tcp from any to any port smtp -> 127.0.0.1 port
spamtrapport

Then, try a TCP handshake from the host in <white> with that system (on smtp
port in this case) - sending the first segment with ACK will trigger the panic.

Is collecting a core dump still important? If yes, then please let me know,
preferably today, before 10:00 AM Zulu Time.
