found a segfault in python3 / py.test

segfault.py

#needs py.test and needs unittest
# python -m py.test segfault.py
# works with unittest only

    unittest.main()

# except NoneExistent makes a difference!!!!
# ** in def segfault(**body): body makes a difference
# ** in  return function(**kwargs) makes a different

#        with self.assertRaises(TypeError) as context:
#            segfault(**{})  
# removing here the with and only call the segfault function. this makes a difference
