Following example causes double deallocation of a sequence and crashing. class A(list): def __del__(self): next(it) it = iter(A()) next(it) The same is for subclass of tuple, str, bytes and bytearray. Proposed patch fixes this issue. | |||

Updated patch fixes also set, dict and os.scandir() iterator. May be sqlite3 cursor needs a fix, but it is too complicated. | |||

Fixed test for OrderedDict. Tests for list and tuple are moved up to seq_tests.py. | |||

Hi Serhiy, I tried the short example you gave, but it doesn't crash. I'm getting: Exception ignored in: <bound method A.__del__ of []> Traceback (most recent call last): File "./test.py", line 5, in __del__ next(it) StopIteration Exception ignored in: <bound method A.__del__ of []> Traceback (most recent call last): File "./test.py", line 5, in __del__ next(it) StopIteration Traceback (most recent call last): File "./test.py", line 8, in <module> next(it) StopIteration Am I missing something? | |||

It crashes in debug build. | |||

Could anyone please look at the patch? I'm not sure about organizing tests. | |||
