I am using the following Lua dissector to add GIOP to another Ethertype:

local myEthType = 0x89ab
do
   p_myProto = Proto("myProto", "MyProt")
   local g = Dissector.get("giop")
   function p_rus_rmp.dissector(buffer, pkt, root)
      g:call(buffer(36):tvb(), pkt, root)
   end

   -- Register our dissector
   DissectorTable.get("ethertype"):add(myEthType, p_myProto)
end

I get a "C stack overflow" when the trace files are larger (for example 50000
packets). Smaller samples (5 packets) do the job.

It used to work with Wireshark 1.8.15.
It stopped working with Wireshark 1.9.0. The versions 1.10.x and 1.12.x do not
work, too.

If I replace the "giop" with "ip" it works with the newer WS versions and large
packet numbers, too. So it must be something with GIOP.
