This is the maximum length of a Digit_Vector, where
subtype SD is Interfaces.Unsigned_32;
-- Single length digit
type Digit_Vector is array (Length range <>) of SD;
-- Represent digits of a number (most significant digit first)
I think this should give a maximum value of ~10**2000.
I printed out sum'image'length; the last value before the exception was
1937.
