I do know that, under Alsys Ada, you have to worry in about leaking memory.
In a project I worked on, we had a loop similar in format to:

  loop

    Result := Function_Call_returning_variant_record;

  end loop;

We found that there was no reclaimation of memory from the function call
temporary.  It went away when we surrounded the call with a begin end block.
It turned out that Alsys only reclaimed memory when a block went out of scope.
After running several hours, megabytes of memory was being eaten up<G>.
