            Bug ID: 67597
           Summary: [6 Regression] profiledbootstrap failure on ppc64le
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal

          Reporter: trippels at gcc dot gnu.org
  Target Milestone: ---
              Host: powerpc64le-unknown-linux-gnu
            Target: powerpc64le-unknown-linux-gnu
             Build: powerpc64le-unknown-linux-gnu

With:
 % ../gcc/configure --with-cpu=power8 --disable-libstdcxx-pch --disable-libvtv
--disable-libitm --disable-libcilkrts --disable-libssp --disable-libgomp
--disable-werror --enable-multilib --enable-languages=c,c++

I get during stageprofile (with the instrumented compiler):
