Marek Polacek <mpolacek at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mpolacek at gcc dot gnu.org --- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> --- I still see 68395.ii:96:11: error: ‘cpt_MappableElement’ does not constrain a type with -std=gnu++17 -fconcepts but with -std=gnu++20 I see another error too, so it's unclear to me if we should try to fix this one.
