--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
At first I thought it was a pointer to member function issue but nope it is not
as the following happens too but we need to have have the class as a template
rather than the function:
extern "C" int puts(const char*);

template <typename T>
class myclass {
public:

  static void func(const T&) requires true
  {
     puts("true");
  }

  static void func(const T&) requires false
  {
     puts("false");
  }
};                                                                              

auto mylambda = &myclass<int>::func;
