--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
std::thread is doing the right thing, the problem is definitely in tuple:

#include <tuple>

struct MoveOnly
{
    MoveOnly(MoveOnly&) =delete;
    MoveOnly& operator=(MoveOnly&) =delete;

    MoveOnly(MoveOnly&& ){}
    MoveOnly(){}
};

std::tuple<MoveOnly> t{ MoveOnly{} };
