--- Comment #3 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:0d573c1f002fa77a4483aa9ebe310746a313082e commit r13-6527-g0d573c1f002fa77a4483aa9ebe310746a313082e Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Mar 7 16:28:20 2023 +0100 c++: Fix up ICE in emit_support_tinfo_1 [PR109042] In my recent rtti.cc change I assumed when emitting the support tinfos that the tinfos for the fundamental types haven't been created yet. Normally (in libsupc++.a (fundamental_type_info.o)) that is the case, but as can be seen on the testcase, one can violate it by using typeid etc. in the same TU and do it before ~__fundamental_type_info () definition. The following patch fixes that by popping from unemitted_tinfo_decls only in the normal case when it is there, and treating non-NULL DECL_INITIAL on a tinfo node as indication that emit_tinfo_decl has processed it already. 2023-03-07 Jakub Jelinek <ja...@redhat.com> PR c++/109042 * rtti.cc (emit_support_tinfo_1): Don't assert that last unemitted_tinfo_decls element is tinfo, instead pop from it only in that case. * decl2.cc (c_parse_final_cleanups): Don't call emit_tinfo_decl for unemitted_tinfO_decls which have already non-NULL DECL_INITIAL. * g++.dg/rtti/pr109042.C: New test.
