            Bug ID: 110797
           Summary: GCC rejects std::template same_as<int> form
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: hewillk at gmail dot com
  Target Milestone: ---

#include <concepts>

[[maybe_unused]] std::template same_as<int> auto i = 0;

I accidentally found that GCC rejected the above code, not sure if this is
valid code.

Reduced testcase:
```
namespace tt {
template<typename a, typename b>
concept t = true;
}

tt::template t<int> auto i = 0;
```
