[Bug fortran/44556] New: incorrect error: Stat-variable at (1) shall not be DEALLOCATEd within the same DEALLOCATE statement

["jonathan dot hogg at stfc dot ac dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

Attempting to compile the following code:

module dealloc_test
   implicit none

   type test_type
      integer, dimension(:), allocatable :: array
      integer :: st
   end type test_type
contains

   subroutine test
      type(test_type) :: foo

      deallocate(foo%array, stat=foo%st)

   end subroutine test
end module dealloc_test

generates the following result:
[jhogg@jhogg] ~/src/ma77_ic$ gfortran-4.5 -c temp.f90 
temp.f90:13.33:

      deallocate(foo%array, stat=foo%st)
                                 1
Error: Stat-variable at (1) shall not be DEALLOCATEd within the same DEALLOCATE
statement

This seems to be legal code to me, and is used throughout our Fortran library.
