Wireshark-bugs: [Wireshark-bugs] [Bug 5837] Wireshark (and tshark) crashes on http traffic - dis
https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=5837
--- Comment #2 from Bill Meier <wmeier@xxxxxxxxxxx> 2011-04-17 12:39:53 EDT ---
This crash appears to be somehow related to the recent change in packet-tcp.c
which added a 'tcp.data' field.
The actual crash (in Wireshark 1.4.5) is caused when code in bytes_repr_len()
tries to get the length of a tcp.data FT_BYTES field and finds the
'value.bytes' field to have a NULL ptr.
The funny thing: The crash doesn't occur on my latest Windows SVN version of
Wireshark.
I'll not have any further time today to work on this ....
