On DB2 when binding more than 1 blob in the same statement each subsequent blob overwrites previous one. So instead of [1, 2, 3] we get [2, 3, 3] This happens because of reference between loop variable `$value` and the item in `$this->parameters[]`, which remains after iteration, see `bindLobs` and `bind` methods in `\Doctrine\DBAL\Driver\IBMDB2\Statement`
