Yara build on Alpine Linux fails:

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: https://github.com/VirusTotal/yara/pull/2048

docker image:

python:3.9-alpine

Should be fixed in 833a580430abe0fbc9bc17a21fb95bf36dacf367

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?

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