Are you able to post the code?

Can you please post the specific "FAILED ..." message?  It should
include the function name on which the failure was detected.

Also, what version of John are you adding this format to?  (There are
currently slightly different requirements between magnum-jumbo and
bleeding-jumbo branches.)

There are many possible reasons, ranging from wrong test vectors to code
bugs.  It'd be helpful to see whatever additional info you can post
before we start guessing.
