[Bug ada/32286] New: ICE in dwarf2out with -g: sees Ada f-e unconstrained_array_type node

[baldrick at gcc dot gnu dot org]

The following occurs with svn head and GNAT GPL 2007.

$ gcc -c -g -gnat05 e.adb
+===========================GNAT BUG DETECTED==============================+
| 4.3.0 20070611 (experimental) (i686-pc-linux-gnu) GCC error:             |
| in gen_type_die_with_usage, at dwarf2out.c:12921                         |
| Error detected around e.adb:8                                            |
...

This occurs because a node type that should be internal to the
Ada f-e (unconstrained_array_type) has made its way as far as
gen_type_die_with_usage in dwarf2out.c.

Testcase:

package E is
   type T (S : access String) is null record;
   procedure P (X : T);
end;
package body E is
   procedure P (X : T) is
      S : String renames X.S.all;
      F : String (S'Range);
      for F'Address use S (S'First)'Address;
   begin
      null;
   end;
end;

gcc -c -g -gnat05 e.adb works on 4.1.2, but it ICEs on 4.2 and 4.3.

------- Comment #2 from sam at gcc dot gnu dot org  2007-12-07 12:37 -------
Have you tried with a recent trunk GCC? Your GCC reads "20070611", but with the
current trunk (4.3.0 20071207), I cannot reproduce the bug on
i686-pc-linux-gnu:

% gcc -c -g -gnat05 e.adb

Laurent, which version did you use?

Trunk from 20070611, but if it doesn't show up now (I haven't checked) this
should be marked as fixed on trunk.
