Could you double check this?

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?
