            Bug ID: 60529
           Summary: internal compiler error with allocatable sub-component
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: carlos.a.cruz at nasa dot gov

Using the following compiler release:

GNU Fortran (GCC) 4.9.0 20140309 (experimental)

on the following reproducer:

---
module T_mod
  implicit none
  type :: TS
    integer, allocatable :: i(:)
  end type TS
  type :: T
! The following line causes an internal compiler error.
    type (TS) :: s(1) 
! The following line does not:
!    type (TS), allocatable :: s(:)
  end type T
contains
  subroutine insert(this)
    class(T) :: this
  end subroutine insert
end module T_mod
---

yields an internal compiler error:

repro.F90: In function ‘__final_t_mod_T’:
repro.F90:19:0: internal compiler error: in gfc_conv_descriptor_data_get, at
fortran/trans-array.c:145
 end module T_mod

I am running on a Linux cluster:

Linux discover28 2.6.32.54-0.3-default #1 SMP 2012-01-27 17:38:56 +0100 x86_64
x86_64 x86_64 GNU/Linux

Note that the internal compiler error does not occur with two earlier releases
of gfortran:

GNU Fortran (GCC) 4.9.0 20140105 (experimental)

GNU Fortran (GCC) 4.8.1
