    When an objects repr or str methods return None a TypeError is raised. However if this object is passed to a function and args is called from within pdb, pdb will immediately exit.

    Attached to this is bug_example.py which contains a simple example of how to reproduce this.

    Depending on circumstances this can make debugging difficult.

    exact python version that this happened with:
    Python 3.6.11

    This is true in 3.10 as well. The same happens if __repr__ raises an exception. do_args command doesn't handle exceptions from repr.

    See also bpo-37022.
