"attempt to yield across metamethod/C-call boundary" with LuaJIT but not with Lua

[Szymon Gatner <szymon.gatner@...>]

Hi,

this is my first post on this list so I hope I am following all rules properly.

I just encountered the dreadful "attempt to yield across
metamethod/C-call boundary" error.
Worst part is I am getting different behavior with different
lua51.dll. With original Lua 5.1.4
attached code runs fine - no errors but when LuaJIT 1.1.7 is used error occurs.

My question is: is this code correct? If yes, why LuaJIT reports error?

Code:

#include <iostream>
#include <lua.hpp>
#include <luabind/luabind.hpp>
#include <luabind/yield_policy.hpp>

using namespace std;
using namespace luabind;

void func()
{
  cout << "c func" << endl;
}

int main()
{
  lua_State* L = luaL_newstate();
  luaL_openlibs(L);

  open(L);

  module(L)
  [
    def("func", func, yield)
  ];

  luaL_dostring(L, "function funcWrap() func() \nprint('resumed') end");

  lua_State* coro = lua_newthread(L);

  try
  {
    resume_function<void>(L, "funcWrap");
  }
  catch (error& e)
  {
    luabind::object msg(from_stack(L, 1));

    cout << e.what() << ":" << msg << cout;
  }

  cin.get();
}
