Extended Description

Godbolt shows a clang 10 stacktrace for the following code:
https://godbolt.org/z/8az9zC

I wanted to build a template helper to transform a std::variant of the form
std::variant<type_tag<A>, type_tag<B>, ...>
into:
std::variant<A, B, ...>
.

[wheatman]

This was fixed before 14.0.0
https://godbolt.org/z/aE3foqons

for reference

code

#include <variant>

template <typename T>
struct type_tag {
  using type = T;
};

template <typename... PossibleTypeTs>
auto unwrap(std::variant<type_tag<PossibleTypeTs>...> ts)
    -> std::variant<PossibleTypeTs...> {};

int main() {
  std::variant<type_tag<int>, type_tag<unsigned int>> wrapped_variant =
      type_tag<int>{};

  return std::visit(
      [&](auto &&arg) -> decltype(unwrap(wrapped_variant)) {
        using T = std::decay_t<decltype(arg)>;
        return 0;
      },
      wrapped_variant);
};
