The lastest master is indeed broken on > 1 core. I can't give an exact time as to when a fixed version will be put onto Github, but hopefully in the next month. In the mean time, if you want the latest working version, take anything from July 22nd or before.

Peter Osterlund found the bug for Nemorino, although Laser's bug is somewhat similar (but much worse, since it affects more than just speed). I accidentally made some evaluation tables global instead of wrapping them in per-thread class objects. I don't understand why the slowdown only seems to occur on NUMA machines, though. I would expect it to be slower on all machines.
