            Bug ID: 66898
           Summary: [6 Regression] profiledbootstrap failure on x86
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

On Fedora 22/x86-64, r225875 failed to profiledbootstrap when
GCC was configured with

# PATH=/usr/local32/bin:$PATH
# CC="gcc -m32 -fno-lto" CXX="g++ -m32 -fno-lto"
RUNTESTFLAGS="--target_board='unix'"
/export/gnu/import/git/sources/gcc/configure --with-demangler-in-ld 
--enable-clocale=gnu --with-system-zlib i686-linux --prefix=/usr/gcc-6.0.0
--enable-gnu-indirect-function --disable-werror --enable-libmpx
--with-fpmath=sse
# make -j8 profiledbootstrap CC="gcc -m32 -fno-lto" CXX="g++ -m32 -fno-lto"

with /usr/local32/bin containing 32-bit binutils.  I got

/export/gnu/import/git/sources/gcc/gcc/lto-streamer-out.c: In function ‘void
lto_output_location(output_block*, bitpack_d*, location_t)’:
