    Hi Matthias,

    I can still reproduce it in quite some variety.

    gnat-13-<triplet> as built from src:gcc-13 still contains unversioned
    tools. There are declared conflicts for various gnat-VER, but no
    conflicts for gnat-VER-<triplet>. As a result, there still is an
    undeclared file conflict with gnat-12-<triplet> as built from
    src:gcc-12-cross present in bookworm|trixie|sid and gnat-11-<triplet> as
    built from src:gcc-11-cross present in bookworm|sid.

    I cannot find any such conflicts for gnat-14-<triplet> nor
    gnat-15-<triplet>, because then the defaults are managed via
    src:gcc-defaults.

    I think src:gcc-13 needs to augment its Conflicts from

    Conflicts: gnat-4.9, gnat-5`'TS, gnat-6`'TS, gnat-7`'TS, gnat-8`'TS, gnat-9`'TS,
    gnat-10`'TS, gnat-11`'TS, gnat-12`'TS,

    to

    Conflicts: gnat-4.9, gnat-5`'TS, gnat-6`'TS, gnat-7`'TS, gnat-8`'TS, gnat-9`'TS,

    All the conflicts seem to be there with the triplet?

    This is more subtle in two regards. For one thing, I implied that the
    problem would be fully architecture-generic. It is not. For gnat-13-aarch64-linux-gnu, no problem exists, because there is no gnat-12-aarch64-linux-gnu:amd64 nor gnat-11-aarch64-linux-gnu:amd64.

    For another, the gnat-VER-TRIPLET:ARCH packages are built from different
    source packages. If the TRIPLET matches the ARCH, it is built from
    gcc-VER and from gcc-VER-cross otherwise. Those packages are different.

    So let's move from arm64 to armhf.

    $ apt-cache show gnat-13-arm-linux-gnueabihf:amd64 | grep ^Conflicts
    Conflicts: gnat-10-arm-linux-gnueabihf, gnat-11-arm-linux-gnueabihf, gnat-12-arm-linux-gnueabihf, gnat-4.9, gnat-5-arm-linux-gnueabihf, gnat-6-arm-linux-gnueabihf, gnat-7-arm-linux-gnueabihf, gnat-8-arm-linux-gnueabihf, gnat-9-arm-linux-gnueabihf
    $ apt-cache show gnat-13-arm-linux-gnueabihf:armhf | grep ^Conflicts
    Conflicts: gnat-10, gnat-11, gnat-12, gnat-4.9, gnat-5, gnat-6, gnat-7, gnat-8, gnat-9
    $ apt-cache show gnat-13-arm-linux-gnueabihf:amd64 | grep ^Conflicts
    Conflicts: gnat-10-arm-linux-gnueabihf, gnat-11-arm-linux-gnueabihf, gnat-4.9, gnat-5-arm-linux-gnueabihf, gnat-6-arm-linux-gnueabihf, gnat-7-arm-linux-gnueabihf, gnat-8-arm-linux-gnueabihf, gnat-9-arm-linux-gnueabihf
    $

    As you can see, gnat-13-arm-linux-gnueabihf:armhf does not conflict with gnat-12-arm-linux-gnueabihf and gnat-12-arm-linux-gnueabihf:amd64 does
    not conflict with gnat-13-arm-linux-gnueabihf. Yet both contain
    unversioned tools and would actually produce an unpack error when
    attempting to coinstall them.

    I assume the last is supposed to be for 12?

    Thank you for correctly spotting the copy&paste mistake.

    As you can see, gnat-13-arm-linux-gnueabihf:armhf does not conflict with gnat-12-arm-linux-gnueabihf

    I can see that now.

    and gnat-12-arm-linux-gnueabihf:amd64 does
    not conflict with gnat-13-arm-linux-gnueabihf.

    But your output shows that it does (in the reverse direction)?

    I'm no sure what you mean here. Just lines earlier you appeared to agree
    that the reverse direction was missing the conflict.

    Maybe we can more easily settle the matter given a reproducer.

    $ mmdebstrap unstable /dev/null --verbose --variant=essential --architectures=amd64,armhf --include=gnat-13-arm-linux-gnueabihf:armhf,gnat-12-arm-linux-gnueabihf:amd64

    $

    I'm also attaching a .debdiff for what I think to be the solution here.
    You may find a build with the additional conflicts at https://debusine.debian.net/debian/developers/work-request/89768/.
