Note: compilation was failing because my distribution seems to not have std::clamp, so I added this code right into two files where clamp was used:

template<class T>
const T& clamp(const T& x, const T& upper, const T& lower) {
    return std::min(upper, std::max(x, lower));
}

But it should not be a problem as far as I understand.

Bizarre.

• What version were you compiling, master or a specific tag?
• Can you compile this with rustc? I thought that was only a rust compiler. Regardless, I've got all the intrinsics out of this now so it should be compiler ambivalent.

[shitpoet]

I don't remember now, but it was either master or the last tag 1.5.0.

Anyway, I cloned the master branch again (into a new separate folder) and tried compilation and testing again, with that "fixing" of missing std::clamp in search.cpp and uci.cpp, and... result is the same:

Unfortunately, I don't know how to compile C++ code with rustc, and at least a very quick google search didn't answer for me that question. But if you know how can I try to compile the project using rustc, I would try.
