The 17.2 update is accompanied by updated Command Line Tools,
so, having made a copy of the current CLTs, I let it update.

With GNAT 13.2.0 on Intel macOS 17.2 this happens:

/Users/wf/KDF9/emulation/Testing: chmod 444 ST0

On compiling and running the minimum test case:

with Ada.Direct_IO;
with Ada.IO_Exceptions;
procedure failure is
     package my_IO is new Ada.Direct_IO(Integer);
     use my_IO;
     my_file : File_Type;
Open(my_file, Inout_File, "ST0");
    when Ada.IO_Exceptions.Use_Error =>
        raise program_error with "Open failed to get RW access";
end failure;

I get:

A. with  ”-largs -Wl,-ld_classic” in the linker parameters:

/Users/wf/KDF9/emulation/Testing: failure
raised PROGRAM_ERROR : Open failed to get RW access

This is what should happen.

B. recompiled and relinked without ”-largs -Wl,-ld_classic”:

/Users/wf/KDF9/emulation/Testing: failure
raised CONSTRAINT_ERROR : erroneous memory access


Strangely, this is now the ONLY one out of dozens of regression tests
that fails in this software configuration.
Previously, they all failed at the link stage.
