At runtime: 10.9.5, 10.10.5, and 10.11.6.

Yes, I'm aware of these differences. I'm also aware, as you surely are, that
sometimes behaviour depends (only) on what SDK you link against.
If you scrub to around 43:37 here:
you'll see they specifically refer to "linked on 10.11".
Besides, I both build and run on 10.11.6 and yet I see these message-to-zombie
crashes after removing the setDelegate:nil code.
