Bug ID: 121162
Summary: GNAT hang with `-gcodeview -fgnat-encodings=all` (but
not just with `-gcodeview`)
Product: gcc
Version: 15.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: ada
Assignee: unassigned at gcc dot gnu.org
Reporter: andrew.teylu at vector dot com
CC: dkm at gcc dot gnu.org
Target Milestone: ---
For the following file:
```
package MINIMAL_HANG is
type RANGE_TYPE is range 1 .. 11;
function SOME_FUNCTION (str : String) return String;
end MINIMAL_HANG;
package body MINIMAL_HANG is
type NULL_RECORD is record
null;
end record;
ARRAY_VAR : array (RANGE_TYPE) of NULL_RECORD;
function SOME_FUNCTION (str : String) return String is
begin
return str;
end SOME_FUNCTION;
end MINIMAL_HANG;
```
and with the following steps:
```
gnatchop -w input.txt
gnat-x86_64-windows64-15.1.0-2/bin/gcc.exe -g -gcodeview -c minimal_hang.adb #
doesn't hang
gnat-x86_64-windows64-15.1.0-2/bin/gcc.exe -g -gcodeview -fgnat-encodings=all
-c minimal_hang.adb # hangs
```
Then `gcc` doesn't appear to terminate.
