Consider the following code:

$ cat bug.py
from array import array
class C(array):
    def __new__(cls):
        return array.__new__(cls, 'B', b'abc')
    def __index__(self):
        raise TypeError
x = C()
print(bytes(x))

It works under python 3.5:

$ python3.5 bug.py
b'abc'

but raises a TypeError under python 3.6:

$ python3.6 bug.py
Traceback (most recent call last):
  File "bug.py", line 8, in <module>
    print(bytes(x))
  File "bug.py", line 6, in __index__
    raise TypeError
TypeError

It looks like this was introduced in issue #27704.
