flake8 consumes a lot of RAM and 100% CPU usage

[vyunolbek]

how did you install flake8?

$ pip install flake8

unmodified output of flake8 --bug-report

{
  "platform": {
    "python_implementation": "CPython",
    "python_version": "3.12.3",
    "system": "Linux"
  },
  "plugins": [

      "plugin": "mccabe",

describe the problem

what I expected to happen

flake8 succeeds with no issues
...

sample code

A typical project with multiple folders

commands ran

$ flake8 --config=dir/.config/lint.cfg dir
...

I can't attach what the console outputs, because the computer just shuts down due to lack of RAM. Previously, it returned the RecursionError error: maximum recursion depth exceeded. Now he just goes on the defensive

There's not enough information to reproduce this and I haven't ever seen it behave like this, even on larger projects like openstack
