--
Using some read filters on certain pcaps causes a segfault. I can reproduce the
crash using tshark 2.0.5 or tshark 2.2.0.
To reproduce:
tshark -2 -R 'tcp.stream == 0' -r broken-reduced.pcap
or
tshark -2 -R 'http' -r broken-reduced.pcap
Using -Y does not cause a crash. Some other read filters do not cause a crash,
for example -2 -R 'ssl' and -2 -R 'tcp' work fine.
I have attached the smallest of 3 pcaps that I've seen the problem with.
