And neither do the 3 exes above. The AVX one does execute and initially respond to the UCI command, but it should not execute at all, because the CPU has no AVX support.

All of them are OK on my AMD FX8350 which does have AVX support.

Definitely something wrong with the compiles and not Tirsa's machine. And as Tirsa says, it is probably AVX related.

Yes, see my edited post.
