[Python-Dev] Starting to use gcc-8 on upstream Python project CI


Hi Brett,

Yes, you are right.

If we just change only the test case of the gcc version from 4.8
(default) to 8, that's not difficult.
I wanted to know how we implement the case if we need it.

Okay, as I have not join the Python development, I did not know how
the core developers are using the CI.

Sure, later if anyone does not open the ticket, I will do it submitting the PR.

Thanks for the explanation.

Since it's only used for the code coverage build I don't think  anyone would mind if you changed it. Just open an issue on bugs.python.org and then submit a PR to change it.
