On which version of Alpine do you have this issue?

This is very likely due to musl 1.2.4, a fix is in progress here: #2048

[nivscadafence]

docker image:

python:3.9-alpine

Should be fixed in 833a580

Given that the build is broken on some non-MUSL systems right now as well, like ArchLinux for example, any chance for a point release that includes the fix that could be propagated to the various dependency managers, @plusvic?

[plusvic]

Yes, I think it's time for a new release.
