------------------ Additional Follow-up Comments ----------------------------
In fact only bases 2, 10 and 16 look right.  Others have a bad bignum size 
calculation and overflow in various cases.

Only bases 2, 8, 10 and 16 are documented as supported, though others (below 
16) are not explicitly rejected.  Maybe that should change too.
