(In reply to Sergey Fedorov from comment #14) > (In reply to Eric Gallager from comment #8) With current trunk on a cross to powerpc-apple-darwin9 this reproduces for the runtime ABI 01 - which is used on 32b Darwin. (i.e the code compiles fine for '-m64') A guess would be that we have a conflict between C++ exception handling (DWARF unwinding) and runtime-abi-01 exception handling (set jump / long jump). Probably, there needs to be some way to flag which kind of exception is present. For runtime ABI 02 (64bit) this should not happen - so the only really affected targets are 32b powerpc and i686 Darwin. ===== backtrace for curent trunk: * frame #0: 0x00000001021b78a5 cc1objplus`internal_error(gmsgid="in %s, at %s:%d") at diagnostic.cc:2166:25 frame #1: 0x00000001021b7d8b cc1objplus`fancy_abort(file="/src-local/gcc-master/gcc/objc/objc-next-runtime-abi-01.cc", line=2795, function="objc_eh_runtime_type") at diagnostic.cc:2296:18 frame #2: 0x000000010003dab7 cc1objplus`::objc_eh_runtime_type(type=0x000000011401c5e8) at objc-next-runtime-abi-01.cc:2795:3 frame #3: 0x00000001011501ad cc1objplus`add_type_for_runtime(type=0x000000011401c5e8) at except.cc:683:40 frame #4: 0x000000010114f8c4 cc1objplus`gen_eh_region_catch(t=0x0000000117c3b318, type_or_list=0x000000011401c5e8) at except.cc:424:23 frame #5: 0x0000000101a400bb cc1objplus`::lower_catch(state=0x0000000309267190, tp=0x000000014813f690) at tree-eh.cc:1815:31 frame #6: 0x0000000101a40cfe cc1objplus`::lower_eh_constructs_2(state=0x0000000309267190, gsi=0x0000000309267140) at tree-eh.cc:2107:27 frame #7: 0x0000000101a40e17 cc1objplus`::lower_eh_constructs_1(state=0x0000000309267190, pseq=0x0000000309267188) at tree-eh.cc:2153:27 frame #8: 0x0000000101a40f46 cc1objplus`pass_lower_eh::execute(this=0x000060000260c540, fun=0x00000001480e8678) const at tree-eh.cc:2198:25 frame #9: 0x00000001017b5131 cc1objplus`execute_one_pass(pass=0x000060000260c540) at passes.cc:2641:30 frame #10: 0x00000001017b5570 cc1objplus`::execute_pass_list_1(pass=0x000060000260c540) at passes.cc:2750:28 frame #11: 0x00000001017b5607 cc1objplus`execute_pass_list(fn=0x00000001480e8678, pass=0x000060000260c240) at passes.cc:2761:23 frame #12: 0x0000000100fe00c4 cc1objplus`cgraph_node::analyze(this=0x0000000148128990) at cgraphunit.cc:694:22 frame #13: 0x0000000100fe23d1 cc1objplus`::analyze_functions(first_time=true) at cgraphunit.cc:1247:18 frame #14: 0x0000000100fe5ed4 cc1objplus`symbol_table::finalize_compilation_unit(this=0x0000000114006000) at cgraphunit.cc:2554:21 frame #15: 0x0000000101987ad5 cc1objplus`::compile_file() at toplev.cc:471:41 frame #16: 0x000000010198b4f0 cc1objplus`::do_compile(no_backend=false) at toplev.cc:2126:24 frame #17: 0x000000010198ba34 cc1objplus`toplev::main(this=0x000000030926751a, argc=16, argv=0x0000000309267668) at toplev.cc:2282:18 frame #18: 0x0000000102187a64 cc1objplus`main(argc=16, argv=0x0000000309267668) at main.cc:39:23
(In reply to Iain Sandoe from comment #15) Would be nice to have it fixed, otherwise `jack` is broken: https://github.com/jackaudio/jack2/issues/950 Which, in turn, leaves broken dependencies.
(In reply to Iain Sandoe from comment #15) Iain, any chance of addressing this one? If would have really helped with quite a number of usable software for PowerPC (majority of which are 32-bit, and even on G5 not all software support ppc64 anyway).
