- Subject: lua_error() and C++

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?
