[issue45524] Cross-module dataclass inheritance breaks get_type_hints

[Sergei Lebedev]

Sergei Lebedev <slebedev at google.com> added the comment:

I think the example has a minor typo. 

The crash is reproducible on 3.9 if the last line in bar.py is

    typing.get_type_hints(B.__init__)

instead of

    typing.get_type_hints(B)
