[3.14] gh-149590: Remove faulthandler_traverse (GH-150023)#150088
Merged
Conversation
`faulthandler_traverse` visits Python objects owned by `_PyRuntime`, not by the module instance. With multi-phase init allowing multiple module instances, each instance's GC traversal decrements `gc_refs` on the same runtime-owned objects, driving it negative when two instances are collected simultaneously. (cherry picked from commit 5673748) Co-authored-by: Armaan Vakharia <43391096+armaan-v924@users.noreply.github.com>
