I have a problem with a sub-dissector based on the DCE/RPC protocl when DCE/RPC
reassembles multiple TCP segments to multiple DCE/RPC fragments.
I attached a screenshot in which 3 TCP segments are being reassembled to 2
DCE/RPC fragments. The sum of the TCP payload is 16384 Bytes, however, the
DCE/RPC dissector ends up to create 2 fragments with a sum of 20016 Bytes. As a
consequence my sub-dissector fails.
