[issue31311] SystemError raised by PyCData_setstate() in case __dict__ is not a dict

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

And the following example results in segmentation fault.

import ctypes
class BadStruct(ctypes.Structure):
    @property
    def __dict__(self):
        raise AttributeError

BadStruct().__setstate__({}, b'')

As for change the format given to PyArg_ParseTuple(), I think it can be done only in master. It is better to make a separate PR for this.
