Sorry for being inaccurate there ... My link line used a different version of gcc (g++ -> g++-4.8) than what the objects were created with. g++ chose the linker for me: g++ <object files> <options> -flto ... lto1: fatal error: LTO_tags out of range: Range is 0 to 365, value is 753 After using g++-4.9 as link command, the error no longer appeared. g++-4.9 <object files> <options> -flto ... (Success) (And sorry for digging up an old article - when I encountered the error I found this thread without response. When I solved the issue for me, I thought it could be helpful for others.)
