Newest release not submitting cryptonight shares
I just did a git clone on 2 linux mint 16 machines, compiled fine and seeing record hashrates for i5-4440 (~65 hashes per thread vs 25 on windows) but not submitting any shares (~60 min). 

Windows versions are slower but working fine, old i7 Nehalem with ubuntu server working fine too with newest git so i guess there went something wrong with a cpu optimization...

If i switch from stratum to normal http it sends shares but they are rejected 100%, tested on two pools.

Cheers
