Please revert the fix then, or check the coverity website for the explanation why it thinks that the index can be 15. It does not seem possible from my cursory examination and we don't sandbag the code against impossible errors. It is probably a coverity false positive. christos

I tested my changes with a Linux-formatted disk, and fuzzed several times some fields. It did work.
