            Bug ID: 109798
           Summary: Gnat Bug Detected
           Product: gcc
           Version: 12.2.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
          Assignee: unassigned at gcc dot gnu.org
          Reporter: aj at ianozi dot com
                CC: dkm at gcc dot gnu.org
  Target Milestone: ---

Steps to reproduce:
1) Create test program called "testing.adb" with the following contents:
```
pragma Ada_2022;
procedure Testing is
   type Test_Enum is (apple, orange, banana);
   type Test_Type is record
      The_Type : Test_Enum;
      The_Value : Integer;
   end record;
   type Test_Array is array (Positive range <>) of Test_Type;

   My_Array : Test_Array (1 .. 6) := ( (apple, 5), (orange, 10), (banana, 1),
(orange, 15), (orange, 12), (apple, 5) );
begin

   for I in My_Array'Range
      when My_Array (I).The_Type /= orange
   loop
      null;
   end loop;

end Testing;
```
2) Compile with gcc 12.0 or greater (I tested it with both gcc 12.2.0 or MacOS
and Debian)

The following output occurs and it fails:
```
ⓘ Building testing/testing.gpr...
Compile
   [Ada]          testing.adb

+==========================================================================+

Please include these source files with error report
Note that list may not be accurate in some cases,
so please double check that the problem can still
be reproduced with the set of files listed.
Consider also -gnatd.n switch (see debug.adb).

/Users/ianozi/projects/testing/testing/src/testing.adb

testing.adb:10:04: warning: "My_Array" is not modified, could be declared
constant [-gnatwk]
testing.adb:10:38: warning: array aggregate using () is an obsolescent syntax,
use [] instead [-gnatwj]
testing.adb:10:39: (style) space not allowed
compilation abandoned

   compilation of testing.adb failed

gprbuild: *** compilation phase failed
error: Command ["gprbuild", "-s", "-j0", "-p", "-P",
"/Users/ianozi/projects/testing/testing/testing.gpr"] exited with code 4
error: Compilation failed.
```

I get the same thing on debian, except the gnat bug detected says
```
| 12.2.0 (x86_64-pc-linux-gnu) GCC error:                                  |
| in gnat_to_gnu_entity, at ada/gcc-interface/decl.cc:472                  |
```

Instead of the apple-darwin stuff.

The same thing happens if I remove the "pragma Ada_2022;" from the beginning of
the program and just compile it with the gnat2022 switch. 

Is this happening for anyone else?
I apologize if I'm filing this bug wrong, or if it's a duplicate, it's the
first time I'm doing this.

Kind regards,
AJ.
