Over East's 2♥ rebid what would double mean? I think it shows a 4 card spades suit and tolerance for diamonds. You could argue that South initially passed with say an unbalanced hand with hearts and therefore over 2♥ a double is for penalties. But playing it this way is usually ineffective. So South should double. There again after South bids 2NT, North is easily strong enough to bid 3♠ showing his shape.
