Following up my own message:
<<In its default configuration, GNAT 3.10 does not require you to write
"zillions of pragmas", and guarantees that Program_Error cannot occur.
Now it is true that you can construct programs that are treated as
statically illegal in this default mode, when they are in fact legal,
but in practice we have found that the rules we implement (which basically
assume pragma Elaborate_All if not stated where needed because of access
from elaboratoin code) seem to work for a very large subset of programs.>>
I should say that the one class of dynamic checks that we do not know how
to eliminate results from the use of access subprograms. Obviously this
is a nasty case, since it involves dynamic value tracing, which cannot be
done entirely accurately, even if you attempt it.
