--- Comment #4 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-14 branch has been updated by Jason Merrill <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:749221fac55059a145d3fdaf416fe663a4ee33d9 commit r14-11535-g749221fac55059a145d3fdaf416fe663a4ee33d9 Author: Jason Merrill <ja...@redhat.com> Date: Mon Apr 7 11:49:19 2025 -0400 c++: constinit and value-initialization [PR119652] Value-initialization built an AGGR_INIT_EXPR to set AGGR_INIT_ZERO_FIRST on. Passing that AGGR_INIT_EXPR to maybe_constant_value returned a TARGET_EXPR, which potential_constant_expression_1 mistook for a temporary. We shouldn't add a TARGET_EXPR to the AGGR_INIT_EXPR in this case, just like we already avoid adding it to CONSTRUCTOR or CALL_EXPR. PR c++/119652 gcc/cp/ChangeLog: * constexpr.cc (cxx_eval_outermost_constant_expr): Also don't add a TARGET_EXPR around AGGR_INIT_EXPR. gcc/testsuite/ChangeLog: * g++.dg/cpp2a/constinit20.C: New test. (cherry picked from commit c7dc9b6f889fa8f9e4ef060c3af107eaf54265c5)
