Bug ID: 121163
Summary: GNAT hang with `-g -gcodeview` (but not with just
`-g`)
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 LOCAL_IO is
function GET_NEXT return Integer;
end LOCAL_IO;
package body LOCAL_IO is
type TEXT_TYPE is record
null;
end record;
DESCRIPTORS : array (1 .. 2) of TEXT_TYPE;
function GET_NEXT return Integer is
begin
return 1;
end GET_NEXT;
end LOCAL_IO;
```
and the following steps:
```
gnatchop -w input.txt
gnat-x86_64-windows64-15.1.0-2/bin/gcc.exe -g -c local_io.adb # doesn't hang
gnat-x86_64-windows64-15.1.0-2/bin/gcc.exe -g -gcodeview -c local_io.adb #
hangs
```
Then `gcc` doesn't appear to terminate.
