  "message": "c++: Fix up build_data_member_initialization [PR121445]\n\nThe following testcase ICEs, because the constexpr ctor in C++14\nor later doesn\u0027t contain any member initializers and so the\nmassage_constexpr_body -\u003e build_constexpr_constructor_member_initializers\n-\u003e build_data_member_initialization member initialization discovery\nlooks at the ctor body instead.  And while it has various\ncases where it punts, including COMPONENT_REF with a VAR_DECL as first\noperand on lhs of INIT_EXPR, here there is COMPONENT_REF with\nseveral COMPONENT_REFs and VAR_DECL only inside the innermost.\n\nThe following patch makes sure we punt on those as well, instead of\nblindly assuming it is anonymous union member initializer or asserting\nit is a vtable store.\n\nAn alternative to this would be some flag on the INIT_EXPRs created\nby perform_member_init and let build_data_member_initialization inspect\nonly INIT_EXPRs with that flag set.\n\n2025-11-21  Jakub Jelinek  \u003cjakub@redhat.com\u003e\n\n\tPR c++/121445\n\t* constexpr.cc (build_data_member_initialization): Just return\n\tfalse if member is COMPONENT_REF of COMPONENT_REF with\n\tVAR_P get_base_address.\n\n\t* g++.dg/cpp1y/constexpr-121445.C: New test.\n\n(cherry picked from commit 0ac5a60c37d9a40e8993b8207e904b713e73b5d3)\n",
