Bug ID: 115079
Summary: unexpected error with partial specialization of
template<auto...>
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: 420 at zerberste dot es
Target Milestone: ---
Consider the following code snippet
```cpp
template <typename...>
struct TypeList {};
template <auto...>
struct Proxy;
template <typename U, typename... Ts, Ts U::*... Ptr>
struct Proxy<Ptr...> {
using alternatives = TypeList<Ts...>;
};
struct Bare {
int alt_0;
};
template struct Proxy<&Bare::alt_0>;
```

Clang accepts this, GCC does not. Up until GCC 8 it did provide a slightly more
helpful error message, but I do not think it should error to begin with.
