Flength was called with sequence=35193781; how did it mutate into 35193768? The code in Flength doesn't change the value of sequence (unless it is a cons cell, in which case it wouldn't end up in the "else" code path.) The only way this could happen is if something clobbers the stack.... maybe a compiler bug?
