[New-bugs-announce] [issue22911] Segfault on recursive itertools.chain.from_iterable

[Ian Kelly]

New submission from Ian Kelly:

I expect this should result in a recursion depth exceeded error, not a segmentation fault.

$ cat test.py
import itertools

l = []
it = itertools.chain.from_iterable(l)
l.append(it)
next(it)
$ python3 test.py
Segmentation fault (core dumped)
