I guess XX SOS by the 2♥ bidder? On the OP hand I believed 5♥ to be the right action by West. JLall convinced me of doubling, but I'm not sure when to use it. I mean, 5 card support of partner's suit (which should be al least fourth) and a void in their suit (which is not that bad for doubling since partner is supposed to be long and the double might make them err). So this double is still take-out? Is it optional? Is it 'I have support but don't mind leaving it'?
