property's tp_init has this code:

 if (Py_IS_TYPE(self, &PyProperty_Type)) { Py_XSETREF(self->prop_doc, prop_doc); } else { /* If this is a property subclass, put __doc__ in dict of the subclass instance instead, otherwise it gets shadowed by __doc__ in the class's dict. */ /*...*/ PyObject_SetAttr((PyObject *)self, &_Py_ID(__doc__), prop_doc); /*...*/ } 

This assumes that subclasses of property have a __dict__ (or a __doc__ attribute settable by other means). That is the case when subclassed using the class statement, but might not be true using C.
A C-API reproducer is at https://github.com/wjakob/inheritance_issue/blob/master/inheritance_issue.c

I don't see a good way to fix this. We could:

• document that subclasses need to set Py_TPFLAGS_MANAGED_DICT (or provide a __doc__ descriptor), or
• ignore the AttributeError, unless __doc__ was set explicitly?
