--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Further reduced:
#include <range/v3/algorithm/find.hpp>
struct X { };
using F = int (X::*)() const;
using I = X*;
using R1 = ranges::invoke_result_t<F&, X&>;
static_assert( std::is_same_v<R1, int> );
This fails because R1 is int (X::)() const which is nonsense.

std::invoke is not even used, ranges-v3 provides its own invoke.
