lua_error() and C++

[David Morris-Oliveros <david@...>]

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());

   sm.ModifyState(State::FunkyModification);

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

   // 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?
