             Bug #: 55074
           Summary: error during bootstrap of trunk
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: blocker
          Priority: P3
         Component: bootstrap
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: matt@use.net


On the same machine and same environment where I bootstrap 4.6, 4.7,
google-4.6, and google-4.7, I have not been able to bootstrap trunk as r192821.
It may be worth noting that I see similar errors when I attempt a
profiledbootstrap with google/4_7, but not with any FSF branch or google/4_6.

My configure line:
../gcc-trunk/configure --program-suffix=-4.8 --prefix=/u/mhargett --enable-lto 
--with-fpmath=sse --disable-libmudflap --disable-libssp --enable-gold=yes
--with-mpc=/u/mhargett --with-cloog=/u/mhargett/ --with-ppl=/u/mhargett/
--with-gmp=/u/mhargett/ --with-isl=/u/mhargett --with-mpfr=/u/mhargett/
--enable-cloog-backend=isl CC=gcc-4.7 CXX=g++-4.7 --enable-languages=c,c++,lto

Always results in this error, even without bootstrap-lto, and without
profiledbootstrap just "make -j8":
