Inconsistent behavior with circular import on MacOS

[guyarad]

Bug description

The issue appeared when the code allegedly had a circular dependency. pylint did not complained on a MacOS machine, but did complain on Linux. However, I was able to narrow it down to a file-system (???) issue by demonstrating an inconsistent behavior when running inside a container on a local folder versus a mounted folder (when the host is a MacOS).

I added details and how-to reproduce here

TL;DR - to reproduce on MacOS run:

git clone git@github.com:guyarad/pylint-macos-issue.git
cd pylint-macos-issue
make bug_repro

Configuration

No response

Command used

pylint --recursive=y --disable=W,C0114,C0115,C0116,R0903 -s=n .

Pylint output

Inconsistent - on Linux:

************* Module module1.derived
module1/derived.py:1:0: R0401: Cyclic import (module1 -> module1.derived) (cyclic-import)

But on a MacOS it was successful.

Expected behavior

Consistent behavior when running on a mounted folder and local folder (when all files are identical).
