             Bug #: 52059
           Summary: [4.7 Regression] ICE in gfc_conv_variable
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P3
         Component: fortran
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: jakub@gcc.gnu.org
                CC: mikael@gcc.gnu.org


subroutine baz
  real(kind=8) :: a(99), b
  interface bar
    function bar (x, y)
      integer, intent(in) :: x, y
      real(kind=8), dimension((y-x)) :: bar
    end function bar
  end interface
  b = 1.0_8
  a = foo (bar(0,35) / dble(34), b)
contains
  elemental real(kind=8) function foo(x, y)
    real(kind=8), intent(in) :: x, y
    foo = 1
  end function foo
end subroutine baz

ICEs starting with http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=180906
(and, when b in the call is replaced with say 1.0_8, ICEs in gfc_conv_constant
and when the y argument from y is removed and the caller is adjusted too, ICEs
in gfc_trans_assignment.
