            Bug ID: 62044
           Summary: ICE in USE statement with RENAME for extended derived
                    type
           Product: gcc
           Version: 4.10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reubendb at gmail dot com

Hello,
I am getting an internal compiler error with the following code when using
RENAME list of USE statement with extended derived type. The following reduced
source code reproduce the issue:

$ cat GridImageSilo_Template.f90 
module GridImageSilo_Template
  implicit none
  private
  type, public, abstract :: GridImageSiloTemplate
  end type GridImageSiloTemplate
end module GridImageSilo_Template

$ cat UnstructuredGridImageSilo_Form.f90 
module UnstructuredGridImageSilo_Form
  use GridImageSilo_Template
  implicit none
  private
  type, public, extends ( GridImageSiloTemplate ) :: &
    UnstructuredGridImageSiloForm
  end type UnstructuredGridImageSiloForm
end module UnstructuredGridImageSilo_Form

$ cat UnstructuredGridImages.f90 
module UnstructuredGridImages
  use UnstructuredGridImageSilo_Form, &
        UnstructuredGridImageForm => UnstructuredGridImageSiloForm
end module UnstructuredGridImages

$ cat FileSystem.f90 
module FileSystem
  use UnstructuredGridImages
end module FileSystem

And if I compile them in order:
$ gfortran -c GridImageSilo_Template.f90
$ gfortran -c UnstructuredGridImageSilo_Form.f90 
$ gfortran -c UnstructuredGridImages.f90 
$ gfortran -c FileSystem.f90
