ICE with type hierarchy and length param

I have been away from my Fortran compilers for too long.  As part of getting back into the swing of things, here's an ICE.

MODULE ICE20170607
  IMPLICIT NONE
  
  PRIVATE
  
  TYPE, PUBLIC, ABSTRACT :: GrandParent
  CONTAINS
  END TYPE GrandParent
  
  TYPE, EXTENDS(GrandParent), ABSTRACT :: Parent(num)
    INTEGER, LEN :: num
    REAL :: array_comp(num-1)
  END TYPE Parent
  
  TYPE, EXTENDS(Parent) :: Child
  END TYPE Child
CONTAINS
  SUBROUTINE bar(array)
    REAL, INTENT(IN) :: array(:)
    TYPE(Child(:)), ALLOCATABLE :: tmp
    
    ALLOCATE(Child(SIZE(array)+1) :: tmp)
  END SUBROUTINE bar
END MODULE ICE20170607

Causes grief for the 18 beta too.

Hi Ian,

Hi Ian,

Thank you for the report. I was able to test the code with the same result. This issue is escalated to development for fix.
