Ah, thanks a lot!

Yes, I think adding -w is the easiest solution (after all that's just reverting to the old behavior). Otherwise the test could be changed to pass arguments by pointer like the others, but I didn't dare do that in case it was specifically testing passing by value. I'll submit the -w ASAP, thanks again.
