Hi,

Compiling: aliasing.ads (source file time stamp: 2012-06-20 19:41:48)

      1. package Aliasing is
      2.
      3.    type I is ('a', 'b', 'c');
      4.    for I use (11, 22, 33);              --!
      5.
      6.    type T is range 1 .. 10;
      7.    type Ary is array (I) of aliased T;
      8.    type Ptr is access constant T;
      9.
     10.    Vs : Ary;
     11.    Nm : T renames Vs('b');
     12.    X : Ptr := Nm'Access;
                       |
         >>> prefix of "Access" attribute must be aliased

     13.
     14. end Aliasing;

  14 lines: 1 error

The error goes away when line 4 is commented.
Is this expected behavior or is my compiler confused?
