嵌套的“ static_for”会导致编译器错误

我static_for根据这个问题使用。我嵌套两个static_for循环，进行编译，g++-7 -std=c++1z main.cpp一切正常

#include <iostream>

template <int First, int Last>
struct static_for
{
  template <typename Lambda>
  static inline constexpr void apply(Lambda const& f)
  {
    if constexpr (First < Last)
      {
    f(std::integral_constant<int, First>{});
    static_for<First + 1, Last>::apply(f);
      }
  }
};

template<int i, int j>
void bar(){
  std::cout << i << " " << j << std::endl;
}

int main(){

  static_for<0,3>
    ::apply([&](auto ii){
          static_for<0,3>
        ::apply([&](auto jj){
              bar<ii.value,jj.value>();
            });
        });

  return 0;
}

但是当我将main功能更改为

int main(){

  static_for<0,3>
    ::apply([&](auto ii){
          constexpr int i = ii.value;
          static_for<0,3>
        ::apply([&](auto jj){
              constexpr int j = jj.value;
              bar<i,j>();
            });
        });

  return 0;
}

我收到编译器错误

如果确实是编译器错误，我可能应该报告此错误，但是我不知道如何找出该错误是否已报告。我该怎么办？
