may I suggest reinforcing your test suite using isequal or strcmp to hardcoded diamond strings?
updated!
its unclear what the problem wants plz fix
Needs better test suite rather than just checking random things (which is better suited to be the secondary fail safe not the primary).
This is just lazy from the OP.
