--- Comment #10 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:5237059e04d105fe5441fa7434699eea9a34bf1b commit r12-8378-g5237059e04d105fe5441fa7434699eea9a34bf1b Author: Jason Merrill <ja...@redhat.com> Date: Fri Apr 15 00:11:00 2022 -0400 c++: typeid and instantiation [PR102651] PR49387 was a problem with initially asking for a typeid for a class template specialization before it was complete, and later actually filling in the descriptor when the class was complete, and thus disagreeing on the form of the descriptor. I fixed that by forcing the class to be complete, but this testcase shows why that approach is problematic. So instead let's adjust the type of the descriptor later if needed. PR c++/102651 PR c++/49387 gcc/cp/ChangeLog: * rtti.cc (get_tinfo_decl_direct): Don't complete_type. (emit_tinfo_decl): Update tdesc type if needed. gcc/testsuite/ChangeLog: * g++.dg/rtti/typeid-complete1.C: New test.
