If your TWI code doesn't have any time out and locks waiting for a response then it won't matter if the code is optimised or not I guess. If the device doesn't respond then the code should give up and return an error code of sort. So are you saying that if you turn optimization OFF (the code gets bigger) the TWI still recovers without a device being present and if the optimization is on (any of the 4 levels) then the TWI doesn't recover?
