--- Comment #2 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Marek Polacek <mpola...@gcc.gnu.org>: https://gcc.gnu.org/g:70f2bff43aadd2fcc0595bf9f4bab72647529655 commit r11-8220-g70f2bff43aadd2fcc0595bf9f4bab72647529655 Author: Marek Polacek <pola...@redhat.com> Date: Wed Apr 14 17:57:15 2021 -0400 c++: ICE with bogus late return type [PR99803] Here we ICE when compiling this code in C++20, because we're trying to slam a 'typename' after the ->. The cp_parser_template_id call just before the spot I'm changing parsed A::template A<int> as a BASELINK that contains a constructor, but make_typename_type crashes on that. This patch makes make_typename_type more robust instead of checking for is_overloaded_fn prior calling it. gcc/cp/ChangeLog: PR c++/99803 * decl.c (make_typename_type): Give an error and return when name is is_overloaded_fn. * parser.c (cp_parser_class_name): Don't check is_overloaded_fn before calling make_typename_type. gcc/testsuite/ChangeLog: PR c++/99803 * g++.dg/cpp2a/typename14.C: Don't expect particular error messages. * g++.dg/cpp2a/typename19.C: New test.
