Thanks Javier.

I dont use coroutines and as far as I know I dont get any Lua_State pointer explicitly. Is it hidden somewhere in the stack?

in your C function called by Lua, you get a Lua_State pointer.  be
sure to use this pointer only, and only during the duration of your

In the simple cases, the pointer Lua passes you is the same you
created initially from C; but if you use coroutines anywhere, it could
be a new state, with it's own stack and local frame; but the same
global state, so you must not call an unexpected state.  (at least not
without deep understanding of the way they're all intertwined)
