--- Comment #3 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:97b30a399ef561f6f37a2c08c830fdf3141bb504 commit r13-24-g97b30a399ef561f6f37a2c08c830fdf3141bb504 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.
