            Bug ID: 61750
           Summary: Compiling gfortran.dg/where_operator_assign_2.f90 with
                    -O3 -fwhole-program gives an ICE
           Product: gcc
           Version: 4.10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ipa
          Assignee: unassigned at gcc dot gnu.org
          Reporter: dominiq at lps dot ens.fr

Compiling gfortran.dg/where_operator_assign_2.f90 with -O3 -fwhole-program
gives an ICE for 4.9 and 4.10 configured with the default --enable-checking.

The errors and ICE go away if gcc is configured with --enable-checking=release
or when compiling with -O2 -ftree-vectorize -fwhole-program.
