stack overflow and attemp to call a string value

[sonoro1234]

Hi,

trying to use parseback in a binding of mine https://github.com/sonoro1234/LuaJIT-ImGui

local ParseBack = require 'parseback'
local ig = require"imgui.glfw"
require"anima.utils" --for prtable
local ct = ffi.typeof"ImGuiIO"
prtable(ParseBack.typeinfo(ct))

gives this error

c:\anima\luajit.exe: .\parseback.lua:281: attempt to call a string value
stack traceback:
        .\parseback.lua:281: in function 'typeinfo'
        .\parseback.lua:200: in function 'typeinfo'
        .\parseback.lua:321: in function 'typeinfo'
        .\parseback.lua:186: in function 'typeinfo'
        .\parseback.lua:200: in function 'typeinfo'
        .\parseback.lua:200: in function 'typeinfo'
        .\parseback.lua:321: in function 'typeinfo'
        .\parseback.lua:186: in function 'typeinfo'
        .\parseback.lua:321: in function 'typeinfo'
        .\parseback.lua:186: in function 'typeinfo'
        .\parseback.lua:200: in function 'typeinfo'
        .\parseback.lua:321: in function 'typeinfo'
        .\parseback.lua:186: in function 'typeinfo'
        C:\LuaGL\gitsources\parseback-master\testimgui.lua:19: in main chunk

Then I tried to find this without LuaJIT-ImGui.
This script:

local ParseBack = require 'parseback'
--local ig = require"imgui.glfw"
local ffi = require"ffi"
--require"anima.utils"

ffi.cdef[[
typedef struct A A;
struct A;
typedef void (*uncb)(const char* parent_list, struct A* cmd);
struct A{
	int value;
	uncb cb;
};
]]

local ct = ffi.typeof"A"
ParseBack.typeinfo(ct)

gives:

I've found the harder way that I have the same recursion problem in parseback while trying to consume my generated C structures https://gist.github.com/28bed5c0972a44ee55aef11ee51dbace
