[issue25973] Segmentation fault with nonlocal and two underscores

[Konstantin Enchant]

Konstantin Enchant added the comment:

The problem happens only when "nonlocal __something" in a class method. In your case f2() isn't class method.

More interesting behavior with underscores - https://gist.github.com/sirkonst/6eff694c4546700417ea
