Thank you for reporting. Could you provide a full traceback file to us? It was saved into temporary directory on crashes. The error message let us know the location of the file like this:

Reproduced with following code:

import inspect
import types

class Methodlike():
    def __call__(self):
        pass

method = types.MethodType(Methodlike(), object())
inspect.iscoroutinefunction(method)

It seems iscoroutinefunction() crashes with custom method like objects.
