--- Comment #1 from Sam James <sam at gentoo dot org> --- Created attachment 53275 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=53275&action=edit ccHXKhJc.ii (minimised reproducer) I think I need to re-run cvise because the minimised version doesn't build with Clang, but the original does. For the reduced version: ``` $ g++ -c ccHXKhJc.ii ccHXKhJc.ii: In static member function ‘static bool TypeParameterizedTest<TestSel>::Register()’: ccHXKhJc.ii:19:67: warning: no return statement in function returning non-void [-Wreturn-type] 19 | static bool Register() { new typename TestSel::Bind<int>::type; } | ^ ccHXKhJc.ii: In static member function ‘static bool TypeParameterizedTestSuite<Tests>::Register()’: ccHXKhJc.ii:24:3: warning: no return statement in function returning non-void [-Wreturn-type] 24 | } | ^ ccHXKhJc.ii: In instantiation of ‘void atomic_fetch_flip_basic(Op) [with <template-parameter-1-1> = int; <template-parameter-1-2> = short int; Op = with_order<int>]’: ccHXKhJc.ii:49:47: required from ‘void BasicRelaxed< <template-parameter-1-1> >::TestBody() [with <template-parameter-1-1> = int]’ ccHXKhJc.ii:47:6: required from here ccHXKhJc.ii:39:3: internal compiler error: in pop_local_binding, at cp/name-lookup.cc:2474 39 | for (ref_ atomic : array<Size>{}) | ^~~ 0x72069f pop_local_binding(tree_node*, tree_node*) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/name-lookup.cc:2474 0x72069f poplevel(int, int, int) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/decl.cc:733 0x13a626c do_poplevel(tree_node*) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/semantics.cc:640 0x14f98c5 finish_for_stmt(tree_node*) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/semantics.cc:1399 0x15c481e tsubst_expr(tree_node*, tree_node*, int, tree_node*, bool) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/pt.cc:18768 0x15c428b tsubst_expr(tree_node*, tree_node*, int, tree_node*, bool) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/pt.cc:18507 0x15c41f4 tsubst_expr(tree_node*, tree_node*, int, tree_node*, bool) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/pt.cc:18864 0x163cc24 instantiate_body /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/pt.cc:26466 0x163ab56 instantiate_decl(tree_node*, bool, bool) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/pt.cc:26758 0x1309d40 instantiate_pending_templates(int) /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/pt.cc:26837 0x1302380 c_parse_final_cleanups() /usr/src/debug/sys-devel/gcc-12.1.1_p20220702/gcc-12-20220702/gcc/cp/decl2.cc:5128 Please submit a full bug report, with preprocessed source (by using -freport-bug).
