Subject: Strange behavior on x86 32 build (not sse) for DES

Magnum and I have been working off list on getting multiple builds tested. 

This was  a comment I made on behavior I have seen.


What is happening, is there are certain builds, where the last output line
of john is listing that more hashes were cracked, than number of cracks.  I
see 1321 and 1328 for DES and BigCrypt DES.


-form=DES                        guesses: 1328 time: 0:00:00:01 100.00%

-form=BigCrypt_DES               guesses: 1321 time: 0:00:00:10 100.00%

If I simply run john against the suite test files, the guesses line matches
exactly with what is listed.  However, if I then show or run anything again
against the same test file, it properly lists 1320 passwords found.  It is
simply this accumulation output that is wrong.


It is strange, and may be something recently added.  I have tested 1.7.7
jumbo-1  (before ANY of my changes), and I see the exact same behavior.
1328 for DES and 1321 for BigCrypt, even though only 1320 could possibly be
