--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:1a43af04dd62b80f45700f94ed241347263ed773 commit r14-3204-g1a43af04dd62b80f45700f94ed241347263ed773 Author: gnaggnoyil <gnaggno...@gmail.com> Date: Sat Aug 12 16:16:52 2023 +0800 c++: follow DR 2386 and update implementation of get_tuple_size [PR110216] DR 2386 updated the tuple_size requirements for structured binding and it now requires tuple_size to be considered only if std::tuple_size<TYPE> names a complete class type with member value. GCC before this patch does not follow the updated requrements, and this patch is intended to implement it.
