Patrick Palka <ppalka at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ppalka at gcc dot gnu.org --- Comment #5 from Patrick Palka <ppalka at gcc dot gnu.org> --- That [temp.deduct.partial] wording was changed with wg21.link/cwg1705.
