As reported by Thomas Baudelet on
https://ask.wireshark.org/questions/47671/lua-script-segmentation-fault-11-in-200rc3-on-os-x,
letting a simple lua script running with tshark ends with a segmentation fault.
Running the following script:
local ip = Listener.new("ip")
local ip_src_f = Field.new("ip.src")
function ip.packet(pinfo,tvb,tapinfo)
if (ip_src_f() ~= nil) then
print(tostring(ip_src_f()))
end
end
with this command line:
tshark -q -i 1 -X lua_script:ip.lua
Ends with the following callstack:

epan_dissect * edt, const void * data) Line 108 C
