Hello, My protocol (only to test this problem) specifications : tcp port 20640 message is 5 bytes long command line : tshark -r pb.cap -T text -V --> crash (see pb.1.12.0.txt) ** ERROR:print.c:838:get_field_data: code should not be reached This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. wireshark does not crash and display is ok tshark 1.10.6 does not crash and display is ok (see pb.1.10.6.txt) Plugin dissector code is into packet-tcp-5-bytes.c Regards, Olivier
Hi Olivier, thanks for the report. This is a regression introduced by g21e0a63b2 commit for bug 9169. I proposed a fix (not calling the data dissector when a subdissector claims that the current TCP fragment needs more desegmentation) here: https://code.wireshark.org/review/2350 Regards, Pascal.
