[Bug ada/18727] New: ACATS c43214c fails at runtime

[laurent at guerby dot net]

On x86, x86_64 and powerpc-darwin c43214c fails at runtime. 

Here is a slightly reduced test case that fails at -O2 but works at -O0/-O1 and
often works when slightly changed.

$ gnatmake -O2 p3
$ ./p3
(print garbage, expected WORK)
$ cat p3.adb
-- from ACATS c43214c
with Ada.Text_IO;
procedure P3 is
   SUBTYPE STB IS STRING(1 .. 4);

   GENERIC
      B1 : STB;
   PROCEDURE PROC1;

   PROCEDURE PROC1 IS
   begin
      Ada.Text_IO.Put_Line (B1);
   END;

   X : STB := "WORK";

   PROCEDURE PROC2 IS NEW PROC1 (x);

begin
   PROC2;
END;
$ 

Original ACATS output:

,.,. C43214C ACATS 2.5 04-11-29 10:37:13
---- C43214C CONSTRAINED ARRAY FORMAL GENERIC PARAMETER.
   * C43214C ARRAY DOES NOT CONTAIN THE CORRECT VALUES.
