This creates an array of exactly 0..size_t'last elements -- where size_t'last is at least Integer'Pred(2**16) -- this is quite obviously /NOT/ what you want, and the source of your Storage_Error (as each unsized_C_array takes up so much space).
If I did more interfacing with C I could point you in the right direction, but I can't so someone else will have to weigh in on what a good solution would be.
