Clang compiles the same libstdc++ code without problems.(In reply to Jonathan

This compiles OK:
namespace std::ranges
{
template
class subrange
{
private:
template
struct _Size
{ };
template
struct _Size
{ U _M_size; };

This is the cause:
constexpr
subrange(__detail::__convertible_to_non_slicing<_It> auto __i, _Sent __s,
__size_type __n)
noexcept(is_nothrow_constructible_v<_It, decltype(__i)>
