Research direction
Start with the linked BPO issue 42887 and its discussion; the migrated record names Interpreter Core and Python 3.10 but no files, reproduction test, or patch location. Confirm the 100000 assignments of .sizeof scenario and trace the deletion crash before deciding where a regression test belongs. Done means the reproducer no longer segfaults on deletion and the regression is covered by a test.
