--- Comment #25 from Sam James <sjames at gcc dot gnu.org> --- I am having the same thoughts. It would not be the first time Python had something dubious, like... * https://wiki.gentoo.org/wiki/Project:Python/Strict_aliasing -> https://www.python.org/dev/peps/pep-3123/ * https://github.com/python/cpython/issues/111178 So far, I did not see this failure on any other target (-> makes me think it's a gcc bug). But also, I didn't yet see any other software break on hppa (-> makes me think it might be a Python bug). I tried ubsan on amd64 with Python 3.12 at least and got a lot of different errors, although ubsan does not diagnose aliasing issues... I am undecided myself still.
