Bug ID: 109525 Summary: typo in views::as_const::operator() Product: gcc Version: 13.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: hewillk at gmail dot com Target Milestone: --- ranges#L9027: else if constexpr (is_lvalue_reference_v<_Range> && constant_range<_Tp> && !view<_Tp>) return ref_view(static_cast<const _Tp&>(__r)); According to [range.as.const.overview-2.5], the second condition should be constant_range<const _Tp>, I think?
