[Bug debug/43166] New: [4.5 Regression] ICE in simplify_subreg on fortran code

[jakub at gcc dot gnu dot org]

C { dg-do compile }
C { dg-options "-O -g" }
      SUBROUTINE FOO ()
      INTEGER V1
      COMMON // V1
      END
      SUBROUTINE BAR ()
      INTEGER V0,V1,V2,V3
      COMMON // V1(4),V2(85,4),V3
      DO V3=1,V1(1)
      V0=V2(V3,1)
      END DO
      END
ICEs in simplify_subreg called from expand_debug_expr.  Seems this is Fortran
FE's fault, but I think we should both fix up Fortran FE and make
expand_debug_expr more robust.
