I get this output instead:

$ LC_ALL=3DC ./guix-daemon --version
./guix-daemon: unrecognized option '--version'
Try `guix-daemon --help' or `guix-daemon --usage' for more information.

This is werid, but I think it is because I build guix with lto.

Here is how I build guix:

$ ./bootstrap && ./configure CFLAGS=3D'-O2 -flto' CXXFLAGS=3D'-O2 -flto' LD=
FLAGS=3D'-O2 -flto' && make -j`nproc` AR=3Dgcc-ar NM=3Dgcc-nm RANLIB=3Dgcc-=
ranlib

So, perhaps this is a gcc bug! (not guix's one, we can forget about the
patch)

Could you reproduce it?
