[New-bugs-announce] [issue45648] Better tp_version_tag overflow checks in specializer

[Ken Jin]

New submission from Ken Jin <kenjin4096 at gmail.com>:

Unless I'm mistaken, the current code in Python/specialize.c doesn't check for valid tp_version_tag, so version tag could overflow and it wouldn't know any better.

Ideally, we should add more robust tests for when tp_version_tag overflows, but that's a project for another day.
