--- Comment #70 from Jan Hubicka <hubicka at gcc dot gnu.org> 2011-04-07 19:15:19 UTC --- I can not reproduce the aforementioned elfhack failure. For me build fails later at /abuild/jh/trunk-install/bin/g++ -flto=24 -fuse-linker-plugin -fno-rtti -Wall -Wpointer-arith -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wcast-align -Wno-invalid-offsetof -Wno-variadic-macros -Werror=return-type -Wno-long-long -fno-strict-aliasing -fshort-wchar -pthread -pipe -fexceptions -DNDEBUG -DTRIMMED -g -Os -freorder-blocks -fomit-frame-pointer -fPIC -shared -Wl,-z,defs -Wl,-h,test.so -o test.so test.o === === If you get failures below, please file a bug describing the error === and your environment (compiler and linker versions), and use === --disable-elf-hack until this is fixed. === /abuild/jh/build-mozilla-new11-lto-elfhack/build/unix/elfhack/elfhack -b test.so test.so: terminate called after throwing an instance of 'std::runtime_error' what(): Section index out of bounds make[5]: *** [test.so] Aborted (core dumped) I tend to believe that this is elfhack problem. Only way for me to get similar linker error is to disable the linker plugin and use -fwhole-program. Can you, please, try to build with -save-temps -fdump-ipa-cgraph and attach the produced *.res and *wpa*cgraph files?
