Possible regression?

I’m unsure about that as I never wrote that logic for another Nuitka version.

This is part of the hotfix release 1.2.2 that I just made.

Thanks for your report, this is fixed on the factory branch, which is a development version under rapid development. You can try it out by going here: https://nuitka.net/doc/factory.html

Feedback if this is working is very welcome, just please do not share plans of doing it, but rather confirmations or denials of it working.

This is very likely to lead to a hotfix 1.2.2, with a rebase once this is proven stable.
