            Bug ID: 65597
           Summary: ICE in build_outer_var_ref, at omp-low.c:1043
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: openmp
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: burnus at gcc dot gnu.org

The following Fortran program causes an ICE with -fopenmp; it doesn't with
-fopenmp-simd nor does the equivalent C program ICE:


 !$omp do simd collapse(1)
