3.12.7: gh-113993 backported without subsequent fixes, causing python3: Objects/unicodeobject.c:15018: intern_common: Assertion _Py_IsImmortal(r)' failed.` #124887
Description
Activity
Ah, this problem again.
assert(_Py_IsImmortal(...))breaks stable ABI extensions -- we're supposed to useassert(_Py_IsImmortalLoose(...)). IIRC, that PR took a while to backport, so there's a chance that it predated_Py_IsImmortalLoose. cc @encukouI missed this in the big backport. My apologies :(
Thank you!

uv'scargo test:Backporting 281ffb6 seems to fix the immediate issue but I haven't checked for more regressions.
