--- Comment #5 from Drea Pinski <pinskia at gcc dot gnu.org> ---
Note I think it was working by accident in GCC 4.9 and before.  Chosing the
aliasing info for the load from int64_t . But then again it is hard to see if
the issue is coming via the path which PR 125683 fixed or the path which is
still broken.  Once I debug this further I can see when is the regression
really being caused.

Note also until GCC 15 (including 15), pre/VN-hoisting would use the correct
aliasing which is why `-fno-tree-pre -fno-code-hoisting` is needed there too.
