I have cython file which is using PyObject_GenericSetAttr Now in my script I am using that function to generically delete an attribute by passing a NULL as the last value (this is proper way to trigger a generic delattr in the Python c-api)
I would have thought the proper way to do that was to use PyObject_DelAttr, which Pyrex exposes as delattr(). I don't think PyObject_GenericSetAttr is even meant to be called directly -- it's intended for filling the tp_setattr slot of type objects.
This causes a segfault because the NULL is getting increfed via Py_INCREF instead of Py_XINCREF.
I would recommend against trying to "fix" this. You got away with it before because you happened to be passing the NULL value directly to a function which is expecting it. But casting NULL to an object reference is not something that should be encouraged, because in any other context it would quickly lead to disaster. -- Greg _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
