Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Known to work|12.3.0 |13.1.0 Keywords| |needs-bisection --- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Someone should do a bisect on this; note 13.1.0 is correctly working and the libstdc++ patch is there already. I suspect this is improved by the VRP work in GCC 13 and can't be backported to GCC 12.
