Deprecated warning

Hi, with WP_DEBUG it shows this message of warning:

Deprecated: Assigning the return value of new by reference is deprecated in /home/user/public_html/wp-content/plugins/striper/stripe_gateway.php on line 205

Which is:

202     public function process_payment($order_id)
203     {
204         global $woocommerce;
205         $this->order        = &new WC_Order($order_id);
206         if ($this->send_to_stripe())
207         {

thanks !
