The enum stubs for Python 2 are slightly different from Python 3. The fix in #10412 didn't quite work in Python 2 mode, since `IntEnum` doesn't define `__new__`, and the `__new__` from `builtins.int` is found instead. Work around this by skipping any `__new__` methods found in built-in types. I gave up trying to write a test case for this. It's tricky because `enum` is in Python 3 stdlib but not in Python 2 stdlib.
