            Bug ID: 92960
           Summary: ICE tree check: expected tree that contains 'decl
                    minimal' structure, have 'component_ref' in
                    add_decl_as_local, at fortran/trans-decl.c:261
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal

  Target Milestone: ---

Affects versions down to gfortran-8 :


$ cat z1.f90
program p
   type t(n)
      integer, len :: n
      character(n) :: c
   end type
   type(t(:)), allocatable :: z
   allocate (t(7) :: z)
   associate (y => z%c)
      ! print *, y
   end associate
end
