Bug#973295: command4 autopkg test fails with 3.8 and 3.9 as supported

[Matthias Klose]

Package: src:pybind11
Version: 2.5.0-5
Severity: serious
Tags: sid bullseye
User: debian-python at lists.debian.org
Usertags: python3.9

command4 autopkg test fails with 3.8 and 3.9 as supported

the build picks up 3.9, but the test then runs with 3.8:

the test dependency for that test should be just python3-dev.
