[issue43190] < test.support > check_free_after_iterating( ) causes core dump in handling iteration.

[Yang Feng]

New submission from Yang Feng :

In the following program, we call check_free_after_iterating( ) twice, in the 
second time, we recursively call function test_free_after_iterating(). Python 
interpreter crashes.
+++
import unittest
import test.support

class UnicodeTest(unittest.TestCase):
pass

def test_free_after_iterating():
ut = UnicodeTest()
test.support.check_free_after_iterating(ut, iter, str)
test.support.check_free_after_iterating(str, test_free_after_iterating(), 
str)

test_free_after_iterating()
