Re: why lua need a dummy node?

[Xavier Wang <weasley.wx@...>]

I have noticed that will makes multi-vm fail. although I don't meet this issue myself before, it makes my project fail when I tried it. So I try to solve this problem:

  - use NULL instead of dummynode

  - add dummynode's pointer to lua_State (just add it to global state is enough)

 But both of solution has its disadvantage :(

I'm using luaL_checkversion now.

Xavier Wang.
