As Joan indicated, the .pcap file seems pretty messed up. ;)
Reading this file is essentially a stress test (aka a "fuzz-test") for
Wireshark/Tshark.
Data in frame #43 caused the fcoe dissector to pass an invalid buffer length
parameter to a function which computes a crc on a buffer.
I've committed a fix (SVN #29505) for the crash; Essentially: certain of the
crc calculation functions now do some additional validation of the length
parameter they receive.
(I'll commit a second fix in a day or so to add some additional defensive
coding to the fcoe dissector itself).
Thanks for the report.
