This looks to be a problem in handling UNWRITTEN extents,
and this one seems to be an UNWRITTEN at that contains EOF (hmm).

Don't know the right fix to this one, but you can try avoiding
this bug by creating the FS without support for unwritten:
I believe the option is "-d unwritten=0" to mkfs_xfs.
