Isn't that the usual case?  One can't use newer gnat to build older gnat, and
one can't use way too old gnat to build gnat either?

If you mean that you are building version X of gcc version version Y (newer
than X) of gcc/gnat, then this is as expected and documented: this combination
will not always work and isn't supported. You need to use version X or less
recent to build GNAT.

See https://gcc.gnu.org/install/prerequisites.html (GNAT section).

If this is not what you meant, can you clarify?

Closing, assuming your GNAT base compiler is indeed too recent.
