            Bug ID: 64116
           Summary: ice with -O3 -fgraphite-identity on bootstrap
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hete2 at gmx dot de

My System: Ubuntu 14.04 on a  Intel(R) Core(TM) i3-2120 CPU @ 3.30GHz

Configuring with --with-arch=native and using -O3 -fgraphite-identity -pipe as
BOOT_CFLAGS i get an ICE in Stage 2:

I get the same result using gcc-4.9-20141126

Using -O2 -fgraphite-identity -pipe as BOOT_CFLAGS there is no ICE.

Configuring with --enable-checking=valgrind --with-arch=native and using
additionally -j 3 as make option, i get
