--- Comment #2 from Hana Dusíková <hanicka at hanicka dot net> ---
Same error is also triggered by template partial specialization:
```
template <int N> struct literal {
constexpr literal(const char (&input)[N]) noexcept { }
constexpr literal(const literal &) noexcept { }
};
template <literal Name, int id> struct field { };
template <literal Name> struct field<Name, 1u> { };
```

Short test from Bug 97751:
template <int N>
struct use_as_nttp {};
template <use_as_nttp Value>
struct has_nttp {};
template <use_as_nttp Value>
using has_nttp_2 = has_nttp<Value>;

c++: Fix deduction from auto template parameter [PR93083]
The check in do_class_deduction to handle passing one class placeholder
template parm as an argument for itself needed to be extended to also
handle
equivalent parms from other templates.
gcc/cp/ChangeLog:
PR c++/93083
* pt.c (convert_template_argument): Handle equivalent placeholders.
(do_class_deduction): Look through EXPR_PACK_EXPANSION, too.
gcc/testsuite/ChangeLog:
PR c++/93083
* g++.dg/cpp2a/nontype-class40.C: New test.
