--
Running "tshark -2 -r linkDownFragmented.pcap -R snmp -w out.pcap" causes a
segmentation fault. linkDownFragmented.pcap is attached and contains two frames
with the two fragments of a single SNMP trap.
The idea was to see whether -2 would put all the fragments of the SNMP messages
in the out.pcap as described in
http://article.gmane.org/gmane.network.wireshark.user/15272
(gdb) run -2 -r linkDownFragmented.pcap -R snmp -w out.pcap
