When I tried to test Bro in off-line with TCP dump file, I met
segmentation falut error.
The tcpdump was captured using "Targa2.c" with all supported attacks.
Also, I used the "my own.bro" in accordance with former mailing list
written by Vern about off-line test.
What I used command is as follows:
./bro -r "dumpfile" "my own.bro"
refer to "my own.bro"
