--- Comment #13 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:9b7ab853bf33106fd0539e36d6ce7730269026e1 commit r12-2873-g9b7ab853bf33106fd0539e36d6ce7730269026e1 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Aug 12 09:16:13 2021 +0200 c++: Fix ICE on defaulted spaceship with pointer return type [PR94162] The spaceship-synth-neg6.C testcase ICEs because we call cat_tag_for on the explicit return type, but pointer types don't have TYPE_LINKAGE_IDENTIFIER. The patch fixes that by checking for CLASS_TYPE_P only and also adds verification that it is in std namespace, so we don't return non-cc_last for my_namespace::partial_ordering. The g++.dg/cpp2a/spaceship-synth11.C testcase is from a PR that has been fixed with r12-619-gfc178519771db508c03611cff4a1466cf67fce1d (but not backported to 11). 2021-08-12 Jakub Jelinek <ja...@redhat.com> gcc/cp/ PR c++/94162 * method.c (cat_tag_for): Return cc_last for !CLASS_TYPE_P or for classes not in std namespace. gcc/testsuite/ PR c++/99429 * g++.dg/cpp2a/spaceship-synth11.C: New test.
