Coroutines and lua_close()

["kathrin_69@..." <kathrin_69@...>]

Hi,

if I've this code:

lua_State* pParent = luaL_newstate();
lua_State* pChild = lua_newthread(parent);
lua_close(pChild);

It seems like the last command also destroys the parent VM (all access 
to it after the call to lua_close results in access to non allocated 
memory).

So given the code above: Is there any difference between calling 
lua_close() on pChild or on pParent?
I know that I've not to call lua_close(pChild); to cleanup anything, 
because coroutines are subject to GC. I'm just asking to get better 
understanding of inner mechanics.

Thank you and regards
