            Bug ID: 109670
           Summary: SYSTEM.PERFECT_HASH_GENERATORS.TOO_MANY_TRIES
                    compilation error on 32bit Windows starting with GCC
                    13
           Product: gcc
           Version: 13.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada

  Target Milestone: ---

Updating from 12.2.0 to 13.1.0 we are encountering build errors for all ada
packages on 32bit Windows, all failing with something like:

raised SYSTEM.PERFECT_HASH_GENERATORS.TOO_MANY_TRIES : s-pehage.adb:693
gnatmake: "broken.adb" compilation error

I've reduced one ada example that fails down to:

```
with GNAT.Spitbol.Patterns;
procedure Broken is
   M : GNAT.Spitbol.Patterns.Match_Result;
   type Header_Symbol is (None, Name, Attr, Conv, Prag);
begin
   null;
end Broken;
```

With GCC 12.2.0:

```
$ gnatmake.exe broken.adb
gcc -c broken.adb
gnatbind -x broken.ali
gnatlink broken.ali

```

With GCC 13.1.0:

```
$ gnatmake.exe broken.adb
gcc -c broken.adb

raised SYSTEM.PERFECT_HASH_GENERATORS.TOO_MANY_TRIES : s-pehage.adb:693
gnatmake: "broken.adb" compilation error
```

If there is any more info that I can provide or things I can try out please let
me know.
