You have run into the basic flaw with Pragma ELABORATE.
Its usefulness is severely limited given its current
semantics. It would be much more useful
if a pragma ELABORATE of a unit implied a pragma ELABORATE
of all of the units its body "with"s. Ada '88?
Nevertheless, most compilers implement "friendly"
elaboration order so you won't necessarily run
into the problems. It turns out that the ACVC's
made the same assumption, that pragma elaborating
package Report was sufficient to avoid PROGRAM_ERROR.
In fact, Report "with"s Text-IO, so it is quite possible
that a call on Report during elaboration will die
somewhere in Text-IO with PROGRAM_ERROR.
The newest ACVC suite includes a pragma ELABORATE(Text_IO);
on the report package body.
