Hi Utz - I verified this here as well... in fact it happens before 8
exabytes.  :)  Also, for some sizes, the full sequence of 1-100 was not
in the file.   Looks like something is wrapping around and obliterating
parts of the superblock?

Looks like an interesting problem, but one I might not get to
immediately, working on other more pressing things - just stay away from
those 8 exabyte files for a little while! :)
