Crash on format comments and staticmethod

[AA-Turner]

Describe the bug

Black crashes when run with the input below, I was asked to report a bug. Searched issues for staticmethod and I wasn't able to find a duplicate bug.

To Reproduce Steps to reproduce the behavior:

Run black on the following minimal reproducer:

class A:
    def f(self):
        # fmt: off
        pass
        # fmt: an

    @staticmethod
    def g():
        pass

Expected behavior Not to crash!

Does this bug also happen on master?

Tried on black.now.sh and got the same error.

Hey thanks for the bug report, but I'll be closing as it's a duplicate of #569.

[AA-Turner]

Sorry, must have missed that. Thanks!

[AA-Turner]

Just realised after re-reading that I typed an with an A not on - sorry for the noise. Will keep an eye on #1817.

Thanks for maintaining Black!
