It's not a bug.  Here's a test case.
The size of 'big' is 2**40 - 2**30 bytes, and 'bigger' is one byte bigger.

        $ ls -l big bigger
        -rw-rw-r-- 1 eggert faculty 1098437885952 2006-05-31 10:20 big
        -rw-rw-r-- 1 eggert faculty 1098437885953 2006-05-31 10:20 bigger
        $ du -h --apparent big bigger
        1023G   big
        1.0T    bigger

Also, I'm still leery of assuming properly scaled input.
Is it that much harder to implement it correctly without that assumption?
