From Lenard Lindstrom in issue 10001 (closed as dupe of this issue): The ~Py_buffer.obj field is undocumented. Yet memoryview, that acts as a wrapper, includes the field in gc traversal. Also, if the field is not initialized by bf_getbuffer its value can be indeterminate. For memoryview the gc can crash (see attached C demo program).
