--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Patrick Palka <ppa...@gcc.gnu.org>: https://gcc.gnu.org/g:2c60368ab5706a870a1a3be190acc4d673672c30 commit r14-2421-g2c60368ab5706a870a1a3be190acc4d673672c30 Author: Patrick Palka <ppa...@redhat.com> Date: Mon Jul 10 10:59:40 2023 -0400 c++: redeclare_class_template and ttps [PR110523] Now that we cache level-lowered ttps we can end up processing the same ttp multiple times via (multiple calls to) redeclare_class_template, so we can't assume a ttp's DECL_CONTEXT is initially empty. PR c++/110523 gcc/cp/ChangeLog: * pt.cc (redeclare_class_template): Relax the ttp DECL_CONTEXT assert, and downgrade it to a checking assert. gcc/testsuite/ChangeLog: * g++.dg/template/ttp37.C: New test.
