--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:6c703b4eb68cbc32de1d62e5b573cb1b9857af29 commit r14-7255-g6c703b4eb68cbc32de1d62e5b573cb1b9857af29 Author: Jonathan Wakely <jwak...@redhat.com> Date: Sat Jan 13 12:13:33 2024 +0000 libstdc++: Use variable template to fix -fconcepts-ts error [PR113366] There's an error for -fconcepts-ts due to using a concept where a bool NTTP is required, which is fixed by using the vraiable template that already exists in the class scope. This doesn't fix the problem with -fconcepts-ts as changes to the placement of attributes is also needed. libstdc++-v3/ChangeLog: PR testsuite/113366 * include/std/format (basic_format_arg): Use __formattable variable template instead of __format::__formattable_with concept.
