A few tests used this construction. Since this usage was allowed by the Concepts TS, we only give an error in C++20. gcc/cp/ChangeLog: DR 625 PR c++/97479 * parser.c (cp_parser_type_id_1): Reject using auto as a template-argument in C++20. gcc/testsuite/ChangeLog: DR 625 PR c++/97479 * g++.dg/cpp0x/auto3.C: Update dg-error. * g++.dg/cpp0x/auto9.C: Likewise. * g++.dg/cpp2a/concepts-pr84979-2.C: Likewise. * g++.dg/cpp2a/concepts-pr84979-3.C: Likewise. * g++.dg/cpp2a/concepts-pr84979.C: Likewise. * g++.dg/DRs/dr625.C: New test.
