--- Comment #5 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:af8656be8df68ac26840f7844430fd595255ebd2 commit r10-7236-gaf8656be8df68ac26840f7844430fd595255ebd2 Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Mar 18 08:53:23 2020 +0100 c++: Diagnose a deduction guide in a wrong scope [PR91759] The following testcase is accepts-invalid since r7-6608-ga56c0ac08242269b. Before that change we had this "deduction guide %qD must be declared in the same scope as %qT" diagnostics for it, after the change it is expected to be diagnosed in set_decl_namespace at the not_found: label in there. On this testcase nothing is diagnosed though, because set_decl_namespace isn't called at all, as in_namespace is NULL. The following patch restores the old warning but does it only in case we don't call set_decl_namespace. 2020-03-18 Jakub Jelinek <ja...@redhat.com> PR c++/91759 * decl.c (grokfndecl): Restore old diagnostics about deduction guide declared in different scope if in_namespace is NULL_TREE. * g++.dg/cpp1z/class-deduction72.C: New test.
