<pre>Reduced example:
#include <compare>
struct X
{
auto operator<=>(X const&) const = default;
auto operator==(int i) const;
};
bool f(X x) {
return x == x;
}
clang trunk rejects this saying no matching candidate. The presence of the
unrelated operator== seems to prevent the generation of X::operator==(X const&)
const from the defaulted <=>.</pre>
