I've had to fix the outline/bookmark loop problem before. It is quite an unexpected problem. There are billions of documents out there and who knows how many different pdf generators or editors (writing a pdf is easy, reading a pdf is insanely difficult). I've had normal non-malicious documents where the software trying to merge documents or move pages has caused the outline/bookmark tree to have a loop.
