This was a similar problem to your previous one: a bug in the auto-
possessifying code. It was checking the tables only for characters less
than 127, when it should have been less than 255. I have committed the
fix (SVN 962) and added some test cases (luckily pcretest already
contains a set of ISO 8859 tables that could be used for these tests).
