Hi,

  I finished a new dissector and it successfully displays everything on Linux 8.0. When I tried on another fresh-installed linux system, it displays only the protocol column and info column in the upper pane correctly. However, there is nothing in the middle pane but "unreassembled packet : proto_name_xxx" shown after IP and TCP packet info. When I click on the "unreassembled packet: proto_name_xxx", the corresponding binary is not highlighted either.

  I found the following comments in packet-tcp.c:

    /*
     * Construct a tvbuff containing the amount of the payload we have
     * available.  Make its reported length the amount of data in the PDU.
     *
     * XXX - if reassembly isn't enabled. the subdissector will throw a
     * BoundsError exception, rather than a ReportedBoundsError exception.
     * We really want a tvbuff where the length is "length", the reported
     * length is "plen", and the "if the snapshot length were infinite"
     * length is the minimum of the reported length of the tvbuff handed
     * to us and "plen", with a new type of exception thrown if the offset
     * is within the reported length but beyond that third length, with
     * that exception getting the "Unreassembled Packet" error.
     */

  Could somebody explain to me and tell me how to solve it?

  Thanks! I really appreciate it.
