[issue14010] deeply nested filter segfaults

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

I'm trying to solve this issue (it seemed easy), but the bug is worse than expected. Python crashed even without iteration at all.

it = 'abracadabra'
for _ in range(1000000):
    it = filter(bool, it)

del it

And fixing a recursive deallocator is more harder than iterator.

What can we do if a deallocator raises RuntimeError due to maximum recursion depth exceeded.
