What is the effect of violating the contiguity attribute of a dummy argument?

Hello,

I am experimenting with the CONTIGUOUS attribute and I found to my surprise that passing a non-contiguous array section via a dummy argument that does have this attribute makes no difference. So I wonder if it should - for instance lead to a runtime error message - or not. I compiled the program below with the flag -check:all to see if any runtime error or warning is issued and none is (using Intel Fortran 15). The program works as if this attribute were not present.

Can someone enlighten me? (I can imagine that the attribute is recognised but does not lead to more efficient code ...)

! chktemp.f90 --
!
module temp
contains
subroutine mytemp( a, n )
    real, contiguous, dimension(:) :: a
    integer, intent(in) :: n

    a(1:n) = 1.0
end subroutine
end module temp

program chktemp
    use temp
    implicit none

    real, dimension(10,10) :: aha

    aha = 0.0

    call mytemp( aha(1,:), size(aha(1,:)) )

    write(*,'(10f5.2)') aha
end program chktemp
