@gaborbernat Can you think of any work arounds for this? Or at least some pointers where to look?
Sadly not 😊 you'll need to debug around the code and understand what's happening.
Here's an updated reproducible flow (no need to run it as a Gitlab runner, tox.ini and requirements.txt are still the same)
Base image:

WORKDIR /

ENV VIRTUAL_ENV=/venv
RUN curl -o virtualenv.pyz https://bootstrap.pypa.io/virtualenv.pyz
RUN python3.11 /virtualenv.pyz $VIRTUAL_ENV --pip=embed --setuptools=embed --wheel=embed --no-periodic-update
ENV PATH="$VIRTUAL_ENV/bin:$PATH"
RUN pip --version
RUN python --version
RUN pip install --upgrade --cache-dir=.pip -r requirements.txt && rm -rf .pip
docker build -t registry.local/base-image:latest -f Dockerfile1 .

RUN tox -vvvvv
docker build -t registry.local/tox-image:latest -f Dockerfile2 .

process "/bin/sh -c tox -vvvvv" did not complete successfully: exit code: 2
(Note I know this is a weird way of running tox (with a Docker RUN command at build time) but it's just an example of how to hit the error.)
Thanks to debugging with @anthonywritescode
The problem is with ENV PYTHONOPTIMIZE 1
If you simply run tox like so, you will get the same error:
PYTHONOPTIMIZE=1 tox -vvv
I have no idea why that might break the world, I would say as of today it's unsupported, however, feel free to put in a PR to make it supported. I will not spend time on making this work. 👍😁
