Hi,
 
I'm using wireshark-1.5.0-34789, and wanted to analyse a 1GB trace file.
 
Tshark complains with 
 
** (tshark.exe:1920): WARNING **: Dissector bug, protocol TCP, in packet
84634: reassemble.c:929: failed assertion "tvb_bytes_exist(tvb, offset,
frag_data_len)"
 
on numerous occasions. The trace was captured with a limit of 200 bytes
per packet; should be enough to always contain the complete TCP header.
IP fragmentation shouldn't happen, as the trace was taken off a network
with MTU 1500 on all ends...
 
Last time I tried the GUI version, it seems to load the file nearly to
completion, until it crashes too.
 
 
I don't know if slicing the trace file will do any good, as that might
remove the evidence as to why the dissector fails. Any hints as to how
to provide the raw data in order to fix this would be very much
appreciated!
 
The error doesn't occur evenly distributed - attached a list of packets
tshark complains about.
 
 
Thanks a lot,
 

Richard Scheffenegger
