Description
I ran the latest mypy from master (commit 13b7573) and I got an internal error. I didn't get this error with mypy version 0.511.
File which caused the traceback: https://github.com/zulip/zulip/blob/master/api/integrations/perforce/git_p4.py
This was the only file I ran mypy on.
I didn't use any extra flags with mypy (except --tb to generate the traceback once I got the internal error).
Here's the traceback:
api/integrations/perforce/git_p4.py: error: INTERNAL ERROR -- please report a bug at https://github.com/python/mypy/issues version: 0.520-dev-13b75737bb41d62ae4e7714704dcda3b446fa9f4
