Seems to be an heisenbug see http://gcc.gnu.org/ml/gcc/2005-04/msg00432.html
changing subject since it no longer ICE on ia64.
Reduced testcase from Richard Kenner, which confirms the bug, follows:
$ cat cxa5012.adb
with Ada.Numerics.Float_Random;
with Ada.Numerics.Discrete_Random;
with ImpDef;
use Ada.Numerics;
procedure CXA5012 is
subtype Discrete_Range is Integer range 1..10_000;
package Discrete_Pack is new Discrete_Random(Discrete_Range);
DState_1 : Discrete_Pack.State;
Not_A_State : constant String := ImpDef.Non_State_String;
begin
DState_1 := Discrete_Pack.Value(ImpDef.Non_State_String);
end CXA5012;
