Am I right, the code is invalid?

This stumps me. I don't know if the code is valid or not.
But these code compiles:
----
v | ::ranges::v3::to<std::vector>;
----
v | ::ranges::v3::to_vector;
----
So I guess the code is more likely to be valid?

Then let's mark it as ICE on valid code.

Looks like the original testcase is indeed valid, but one needs to include
<memory_resource> as well (for pmr::polymorphic_allocator).
Reduced:
template<class T, class U>
struct A { A(T, U); };
template<class T, class U>
using B = A<U, T>;
using type = decltype(B{0, 0});

For libstdc++ the <vector> header only declares the pmr::vector alias, without
defining prm::polymorphic_allocator. That means pmr::vector is an incomplete
type unless you also include <memory_resource>.
This is permitted by the standard, and avoids paying to include
<memory_resource> if you don't plan to use the pmr types.

c++: alias CTAD in unevaluated context [PR101233]
This is the alias CTAD version of the CTAD bug PR93248, and the fix is
the same: clear cp_unevaluated_operand so that the entire chain of
DECL_ARGUMENTS gets substituted.
