--- Comment #2 from Saulius Gražulis <saulius.grazulis at bti dot vu.lt> ---
OK, I can confirm that GNAT 15.0 from the git://gcc.gnu.org/git/gcc.git master
no longer gas the bug, the finalization behaves as expected:

# All objects Dispose'd as intended :)

Sorry for the false alarm, and thanks for the rapid fixes! (Did not expect the
15.0 o have the issue fixed already :)
