So you're complaining that GNU diff is too fast?  :-)

GNU diff uses inode numbers to bypass comparisons of hard links to the
same file.  It results in very fast comparisons.  Perhaps that is what
is happening to you.  If your filesystem is reporting inode numbers
incorrectly, that can cause GNU diff to report incorrect results.
