Fatal error in pylint: Issue with dill 0.4.0 on Python 3.13.1

[uelkerd]

Description

When running pylint with the pylint-django plugin enabled, pylint crashes with a fatal error. This appears to be related to compatibility issues between the current version of pylint (3.3.7), dill (0.4.0), and Python 3.13.1.

Environment

• Python version: 3.13.1
• pylint version: 3.3.7
• astroid version: 3.3.10
• dill version: 0.4.0
• Operating system: macOS

Steps to Reproduce

1. Install the dependencies: pip install pylint==3.3.7 pylint-django
2. Create a .pylintrc file with load-plugins=pylint_django
3. Run pylint on a Python file
4. Observe the fatal error

Expected Behavior

pylint should analyze the file without crashing

Actual Behavior

Infinite recursion in wrap_func and ignore_import_warnings_for_related_fields functions leading to:
RecursionError: maximum recursion depth exceeded

Pylint output

The above exception was the direct cause of the following exception:

Additional Information

This appears similar to previously reported issues:

• Pylint fails on Python 3.11 due to issue in 'dill' package pywbem/pywbem#2948 (fixed by upgrading to dill 0.3.6)
• KeyError while running pylint with parallel job option using dill-0.3.5 uqfoundation/dill#478
• Upgrading from pylint 2.14.5 to 2.15.0 causes django.core.exceptions.ImproperlyConfigured to be raised #370

Temporary Workaround

I've found that commenting out load-plugins=pylint_django in .pylintrc allows pylint to run without crashing.
