--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <[email protected]>: https://gcc.gnu.org/g:66fbe318e2df40ff548bc22a7abe5fa8de88429c commit r16-6475-g66fbe318e2df40ff548bc22a7abe5fa8de88429c Author: Jakub Jelinek <[email protected]> Date: Sat Jan 3 12:15:30 2026 +0100 c++: Fix error recovery for invalid arrays [PR123331] The following testcase ICEs since the conditional eltinit = build2 (INIT_EXPR, ...) has been added to cxx_eval_vec_init_1. If there are errors, eltinit will be error_mark_node and we can ICE during constant evaluation of that. Fixed by skipping it for error operands. 2026-01-03 Jakub Jelinek <[email protected]> PR c++/123331 * constexpr.cc (cxx_eval_vec_init_1): Don't build INIT_EXPR if eltinit is erroneous. * g++.dg/other/pr123331.C: New test.
