After fixing the SHA_BUF_SIZ bug in the -fixes branch (which made about half of the 1500 fail) and merging that to magnum-jumbo, I now probably see the same as you in the latter branch:
form=hmac-sha1 guesses: 1497 time: 0:00:00:00 : Expected count(s) (1500) [!!!FAILED!!!]
.pot CHK:hmac-sha1 guesses: 1493 time: 0:00:00:00 : Expected count(s) (1500) [!!!FAILED!!!]
form=hmacMD5 guesses: 1498 time: 0:00:00:00 : Expected count(s) (1500) [!!!FAILED!!!]
.pot CHK:hmacMD5 guesses: 1493 time: 0:00:00:00 : Expected count(s) (1500) [!!!FAILED!!!]
This happened when I introduced clear_keys() in the hmac SSE2 formats. We could just revert that but I'm very curious why that fails. It might be worth trying to nail it.
