Hi, Thanks for the feedback so far. One other thing that is strange to me is in my quest to understand this issue, I did a sizeof of yaffs_ExtendedTags. It gave me 64 bytes every time weather it contains 18 'unsigned' fields (72 bytes on an ARM XScale) or 12 unsigned's and the rest chars (54 bytes).
