[issue35350] importing "ctypes" immediately causes a segmentation fault

Small update:

After commenting out Py_XDECREF(self->restype) in function CThunkObject_dealloc(PyObject *_self), I can import ctypes without getting a segmentation fault.

static void
CThunkObject_dealloc(PyObject *_self)
{
    CThunkObject *self = (CThunkObject *)_self;
    PyObject_GC_UnTrack(self);
    Py_XDECREF(self->converters);
    Py_XDECREF(self->callable);
    //Py_XDECREF(self->restype);
    if (self->pcl_write)
        ffi_closure_free(self->pcl_write);
    PyObject_GC_Del(self);
}

But I'm afraid I don't know what other effects could result with this change.
