>Description:
        tcpdump dumps core with a long filter expression.  (either on
        the command line or using the -F option)
>How-To-Repeat:
        # echo "port 0 or port 1 or port 2 or port 3 or port 4 or port
5 or port 6 or port 7 \
or port 8 or port 9 or port 10 or port 11 or port 12 or port 13 or
port 14" > /tmp/filter.cf

        # tcpdump -nl -i vio0 -F /tmp/filter.cf
        tcpdump(52915) in free(): bogus pointer (double free?)
0xdfdfdfdfdfdfdfdf

        Same behavior with p0f3 (also using libpcap), from packages:

        # p0f3 -i vio0 "$(cat /tmp/filter.cf)"
        p0f3(59041) in free(): bogus pointer (double free?) 0xdfdfdfdfdfdfdfdf
        Abort trap (core dumped)

>Fix:
        Unknown.
