--- Comment #1 from Iain Sandoe <iains at gcc dot gnu.org> ---
it seems that this is fallout from a recent change in the trunk libgcc unwinder
(which we should not be using on Darwin)

fixed by:

r13-4870-ga846817739c1e7b930d593cd51963d6b46b5dfc6
r13-4883-g163f0f2267370575a9950e7e30a2c9cd72f559f0

and 
https://gcc.gnu.org/pipermail/gcc-patches/2022-December/609110.html

fix this by ensuring that we do not try to use the newly-built libgcc_s
unwinder for Ada executables that also pull in system libraries that refer to
the installed unwinder).

    Ada,Darwin: Do not link libgcc statically on Darwin 8 and 9 [PR108202].

    Normally, GCC executables are built with -static-libstdc++ -static-libgcc
    on Darwin.  This is fine in most cases, because GCC executables typically
    do no use exceptions.   However gnat1 does use exceptions and also pulls
    in system libraries that are linked against the installed shared libgcc
    which contains the system unwinder.  This means that gnat1 effectively has
    two unwinder instances (which does not work reliably since the unwinders
    have global state).

    A recent change in the initialization of FDEs has made this a hard error
    now on Darwin versions (8 and 9) with libgcc installed in /usr/lib (gnat1
    now hangs when an exception is thrown).

    The solution is to link libgcc dynamically, picking up the installed
    system version.  To do this we strip -static-libgcc from the link flags.

            PR ada/108202

    gcc/ada/ChangeLog:

            * gcc-interface/Make-lang.in (GCC_LINKERFLAGS, GCC_LDFLAGS):
            Versions of ALL_LINKERFLAGS, LDFLAGS with -Werror and
            -static-libgcc filtered out for Darwin8 and 9 (-Werror is filtered
            out for other hosts).

fixed (needs r13-4870/4883 if we ever want to back port it).
