           Summary: 4.6.0 fails to link ffmpeg with LTO and gold
           Product: gcc
           Version: lto
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gmarkhor@gmail.com


I am trying to make ffmpeg snapshot. I configure ffmpeg with the following
line:

../configure --enable-shared --cc='gcc -flto -fuse-linker-plugin -fPIC'
--prefix=/home/markhor/ffmpeg/install --arch=x86_64

It fails to build with
LD    libavcodec/libavcodec.so.53

original declaration [enabled by default]

--cc='gcc -flto -fPIC' fails the same way. Snapshot is successfully built
without LTO with the BFD linker.
