help('modules') is used

-----------------------+------------------------------------
 In an interactive Python3 session, I typed `help('modules')` at the
 prompt.

 After a couple of seconds Python crashed with a SEG Fault.

 I copied `pydoc.py` from the Macports folder to a folder where I could
 edit it.

 I modified `pydoc.py` like this:
 {{{
 Please wait a moment while I gather a list of all available modules...

 ''')
             modules = {}
             def callback(path, modname, desc, modules=modules):
                 print(path, modname) # <<< Debugging statement >>>
                 if modname and modname[-9:] == '.__init__':
                     modname = modname[:-9] + ' (package)'
                 if modname.find('.') < 0:
                     modules[modname] = 1
 }}}
 I then ran my modified pydoc.py as a standalone Python script with the
 appropriate command to generate a list of modules. A long list of
 debugging statements was displayed and then Python crashed.

 I searched Macports for the module which was causing the crash and I found
 it was in py311-pyobjc. I deactivated py311-pyobjc and tried again. This
 time the list of modules did not crash.

 I have also tested this with python310 with the same result.
