I bet on a regression caused by bpo-22273, commit/16c0f6df62a39f9f7712b1c0577de4eefcb4c1bf.

ARMv7 Debian buster 3.7:

Yes, sorry for the noise - I'm fixing it, and will close this issue once all done.

Closed, as these buildbots are now green. This was addressed via changes to the original PR for bpo-22273.
