Unfortunately the way Ada does this is by allocating enough room for
'object' to hold any possible size -- 2**31 bytes -- this will break
your stack!

You could use a sensible max size and allocate on the heap for larger
objects.

Or you may be able to hold Dynamic_Whatever_Array instances in an
Ada.Containers.Indefinite_<something>.
