Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- This is to be expected. Right now GCC only implements the P1306R5 paper and a smaller part of the P2686R4 paper (only the part where one can specify constexpr or constinit on structured bindings, not the constexpr references to automatic vars part of the paper). See PR117784 for more details. Only when P2686R4 will be fully implemented these testcases will work with constexpr.
