            Bug ID: 65571
           Summary: [4.8/4.9 Regression] ICE for array of a derived type
                    with allocatable array in derived type object
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mandrew9 at vt dot edu

Created attachment 35140
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35140&action=edit
small test case (source code)

Description: 
Create a derived type object (test_t) that contains an array of a derived type
(arraylist_t). This derived type (arraylist_t) contains an allocatable array.
Whenever the object is referenced (as in test_routine), an ICE is thrown.
Replacing the allocatable array in the derived type (arraylist_t) with an
explicit shape array (as shown below) allows the module to compile.

test_mod.f95 (Also attached):
========================================
module test_mod
  implicit none

  type :: arraylist_t
    real, allocatable :: array(:)
!    real              :: array(5)
  end type arraylist_t

  type :: test_t
    type(arraylist_t) :: test_list(3)
  contains
    procedure :: test_routine
  end type test_t

contains

  subroutine test_routine(test_var)
    class(test_t), intent(in) :: test_var
  continue
    ! Do stuff
  end subroutine test_routine
end module test_mod
========================================
Compiler:     gcc version 4.9.2 (Ubuntu 4.9.2-0ubuntu1~14.04)
System:       Ubuntu 14.04
========================================
Command line: gfortran test_mod.f95
Output:
test_mod.f95: In function ‘__final_test_mod_Test_t’:
test_mod.f95:22:0: internal compiler error: in gfc_conv_descriptor_data_get, at
fortran/trans-array.c:145

--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed on 4.9.x, but the test compiles for me on 4.8.x and trunk (5.0,
various revisions and patch status).

I think it is a duplicate of pr64932 and it has been fixed at r 220654 on trunk
and r 220659 for 4.9.
