Amaury Forgeot d'Arc <[EMAIL PROTECTED]> added the comment:
Ah, big numbers that overflow: even if 'start' is (silently) capped to
sys.maxint-1, len(b)-start-len("xx") will wrap and yield a positive
number...
The find/rfind/index/rindex methods have the same problem.
Attached a patch and unit tests, needs review.
