--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Simon Martin <simar...@gcc.gnu.org>: https://gcc.gnu.org/g:4e4c378ac1f923a310fa31be85ed8c0c50e9f5ef commit r15-7096-g4e4c378ac1f923a310fa31be85ed8c0c50e9f5ef Author: Simon Martin <si...@nasilyan.com> Date: Tue Jan 21 13:31:41 2025 +0100 c++: Don't ICE in build_class_member_access_expr during error recovery [PR118225] The invalid case in this PR trips on an assertion in build_class_member_access_expr that build_base_path would never return an error_mark_node, which is actually incorrect if the object involves a tree with an error_mark_node DECL_INITIAL, like here. This patch changes the assert to not fire if an error has been reported. PR c++/118225 gcc/cp/ChangeLog: * typeck.cc (build_class_member_access_expr): Let errors that that have been reported go through. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/constexpr-ice21.C: New test.
