             Bug #: 54638
           Summary: [4.8 Regression] bootstraping 4.7.2 with 4.8 broken:
                    cc1: malloc(): memory corruption
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: markus@trippelsdorf.de


With:
~/gcc/configure --disable-werror --disable-multilib --enable-checking=release
--enable-languages=c,c++

and:
make BOOT_CFLAGS="-march=native -O2 -pipe" STAGE1_CFLAGS="-march=native -O2
-pipe" CFLAGS_FOR_TARGET="-march=native -O2 -pipe"
CXXFLAGS_FOR_TARGET="-march=native -O2 -pipe" bootstrap

I get:
