astroid 2.3.0 is causing RecursionError

[weijiewu8]

My code is very long and I'm not sure which part of the code is causing the RecursionError, but the report seems exactly the same as this one: #2734
The code passes pylint until today when pylint is upgraded to 2.4.0 and astroid to 2.3.0. Downgrading pylint to 2.3.0 and astroid to 2.2.5 resolves the issue.

seeing this as well, here's a concrete reproduction

I'm seeing this in flake8 https://gitlab.com/pycqa/flake8

The easiest reproduction is:

git clone git@gitlab.com:pycqa/flake8
cd flake8
git checkout 121ea4f056fabc82d870cf5deaaf37f035be6d10
tox -e pylint

It (successfully?) finishes but spews 2300+ lines of output

Thank you, I can reproduce the issue as well.

[potiuk]

Yeah. would love that fixed as well!

[PCManticore]

Hey folks, this should be fixed with the recent release of astroid=2.4.2. Can you give it a go and let us know if the recursion error still happens for any of you?
