--- Comment #1 from Lewis Hyatt <lhyatt at gcc dot gnu.org> ---
Thanks, yes the test is problematic because the warnings it looks for are
platform dependent. There is a patch to address it here:
https://gcc.gnu.org/pipermail/gcc-patches/2024-January/644487.html. It's being
tracked at the original PR, so marking as a dupe of that one.
