Here's another example:
template <typename T, typename U>
struct foo {};
template<typename T, typename U>
foo(T&&) -> foo<T, U>;
Clang says:
<source>:5:1: error: deduction guide template contains a template parameter
that cannot be deduced
5 | foo(T&&) -> foo<T, U>;
| ^
<source>:4:31: note: non-deducible template parameter 'U'
4 | template<typename T, typename U>
| ^
But GCC accepts it.
