This is indeed a bug in the calculation of the location of the last
block of a file. I believe that the following patch to head will
fix it.

Peter, can you please test and let me know.

If Peter confirms that it fixes the bug, I will check it into head
and MFC it to 12-stable and 11-stable after a 2-week settle-in time.
