So chipmunk is getting through the core tests now, but instead it
is failing in contrib/pg_visibility [1]:

I find this easily reproducible by setting shared_buffers=10MB.
But I'm confused about why, because the affected test case
dates to Tomas' commit 7db0cd214 of 2021-01-17, and chipmunk
passed many times after that. Might be worth bisecting in
the interval where chipmunk wasn't reporting?
