Confirmed under Windows. Here's the problem (Objects/descrobject.c, near line
1200,
in property_init(...):
/* if no docstring given and the getter has one, use that one */
if ((doc == NULL || doc == Py_None) && get != NULL &&
PyObject_HasAttrString(get, "__doc__")) {
if (!(get_doc = PyObject_GetAttrString(get, "__doc__")))
return -1;
Py_DECREF(get_doc); /* it is INCREF'd again below */
^^^^^^^^^^^^^^^^^^
doc = get_doc;
}
Py_XINCREF(get);
Py_XINCREF(set);
Py_XINCREF(del);
Py_XINCREF(doc);
If the refcount of get_doc drops to zero in the Py_DECREF(), the Py_XINCREF()
shortly after doesn't help ;-).
