    Something similar happened to me once. Two different files with the
    same result from md5sum.

    When I ran md5sum again, it still reported the same results.

    Then when I flushed the page cache and ran it again, it reported
    different results.

    I concluded it was a rare page cache corruption heisenbug. Scary.
