gcc/fortran/:
2010-06-10  Daniel Franke  <franke.daniel@gmail.com>

	PR fortran/44457
	* interface.c (compare_actual_formal): Reject actual arguments with
	array subscript passed to ASYNCHRONOUS dummys.

2010-06-10  Daniel Franke  <franke.daniel@gmail.com>

	PR fortran/44457

Regression tested on i686-pc-linux-gnu.
Ok for trunk?

! PR fortran/44457 - no array-subscript actual argument
!                    for an asynchronous dummy
!

  integer :: a(10), sect(3)
  sect = [1,2,3]
  call f(a(sect))    ! { dg-error "incompatible" }
  call f(a(::2))
contains
  subroutine f(x)
    integer, asynchronous :: x(:)
  end subroutine f
