Bug ID: 115209 Summary: The implementation of concat_view refers to p2542r7 rather than the p2542r8 Product: gcc Version: 15.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: hewillk at gmail dot com Target Milestone: --- It seems that R8 is the final version. Not sure why libstdc++ refers to R7, which makes some updates of R8 not integrated, such as the new relaxed constraints of operator-(const iterator& x, default_sentinel_t).
