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

[Yang Feng]

New submission from Yang Feng <charles.fy at foxmail.com>:

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()
