Alignment of Allocatable Dummy Variable

$

Hi,

I have a subroutine that allocates a workspace for MKL routines, and I want to specify the alignment of the allocated buffer. I'm using the ATTRIBUTES ALIGN directive. This works for e.g. allocatable automatic variables, but doesn't want to work for allocatable dummy arguments. For example, this fails:

subroutine create_workspace ( this, work )
  class(object),              intent(in)    :: this
  real(kind=DP), allocatable, intent(inout) :: work(:)
  !DIR$ ATTRIBUTES ALIGN:64 :: work
  allocate(work(10))
end subroutine create_workspace

The error is

error #6406: Conflicting attributes or multiple declaration of name.   [WORK]

Am I doing something totally wrong here? Is there better way to accomplish this? I'm looking for something that works on both Windows and Linux. The compiler version is 64-bit, 14.0.1.139.

Cheers,

Ben
