--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Confirmed from 6.4.0, 7.2.0 and trunk (8.0). For 4.8, 4.9, and 5 the values for
a%n and a(1:size(a))%n are also wrong.

using

    do i=0,size(a)-1
        print *,a(i)%n
    enddo

displays the expected values.

I am pretty sure there is at least one duplicate, but I cannot find it right
now.
