Can you reproduce this? Looking through src/bin/df/df.c, I can't see
what type of exceptional condition could sneak through. There are some
checks for "impossible" conditions. It's hard to see how the 'size'
can be messed up and yet the 'used' is OK since 'size' is used to
calculate 'used.' And obviously, the size of your file system is not
changing between df(1) runs.
