@Skylion007 pointed me here, thanks!

Looks exactly like this problem: #4054

Note my weird workaround: dd4170d

It would be great if someone got to the bottom of this issue.

Based on this bug report, I'm beginning to think it's a matter of luck that the tests work everywhere else.

A good start would be to add a CI job reproducing this error.
