From my understanding, lua_error() does a longjump. How nicely (if at all) does this play with C++'s unwinding? For example:

int check(lua_State* L)
   StateMaintainer sm(GetGlobalState());


   if (lua_gettop(L) != 2)
      lua_pushstring (L, "Wrong number of args!");

   // something

   return 0;

At the end of this function, C++ will call StateMaintainer's destructor on sm. But if there's an error, and lua_error() is called, then, is it called at all? Or is it silently ignored?
