A bug found ( limited to chess960). Wait a few days for a new compile. I hope to be able to advise you as soon as published.

SSE42 compile appears to be slower than the regular x64 on 2600K@4.5Ghz HT on:
32-bit: 1563kns
32-bit legacy: 1509kns
64-bit: 2091kns
64-bit SSE42: 1718kns (!!!)
64-bit GCC: 2142kns.
Node count is 5416292 in all cases.
I ran the benchmark several times for each build. The results do not change significantly.
