I suppose it would depend on the declaration of the array, but I would not 
expect that to be the case most of the time. Typically, one can initialize 
most Ada data types with a block-copy, which would only be a handful of 
bytes on most target machines. Of course, if you have lots of controlled 
types and tasks, you'd have issues, but those aren't preelaborable anyway 
(some code would need to be executed for them).

That's the sort of thing that having a good relationship with your compiler 
vendor can help with, since it often wouldn't take much tweaking to 
eliminate expensive elaboration code. (It's not something I pay much 
attention to unless a customer asks...)
