            Bug ID: 102654
           Summary: undefined reference to `std::variant<std::string_view
                    >::variant<std::string_view, void, void,
                    std::string_view, void>(std::string_view&&)'
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hewillk at gmail dot com
  Target Milestone: ---

The following code will generate an undefined reference error since gcc-11. I
don't know if this is a bug.

#include <variant>
#include <string_view>

struct my_variant : std::variant<std::string_view> { };
int main() {
  std::string_view s = "hello";
  my_variant v{s};
}
