I had the same arch/gnat/cargs/failure with a shorter example.
with Ada.Containers.Vectors;
procedure Proc is
package Vect is new Ada.Containers.Vectors (Positive, Integer);
type Reco is record
V : Vect.Vector;
end record;
R : Reco;
begin
for E of R.V loop
null;
end loop;
end Proc;

4.8.2-1 produces the expected output for the last trigger
gcc-4.8 -c proc.adb
proc.adb:9:10: iterator is an Ada 2012 feature
gnatmake: "proc.adb" compilation error

This problem is fixed in GCC 4.8 and newer. heap_sieve.adb compiles
successfully with the given command line in 4.8, 4.9 and trunk, whereas
proc.adb compiles successfully in 4.9 and trunk, but it requires explicit
-gnat12 in 4.8.
