我在编译以下代码时遇到问题。

#include <tuple>
#include <vector>

using namespace std;
using Parameter = tuple<int, char[2]>; // compilation fails
//using Parameter = tuple<char[2], int>; // compilation successes

int main() {
    vector<Parameter> v;
    Parameter r;
    v.push_back(r);

    return 0;
}

使用g ++进行编译时，出现以下编译错误：

/usr/include/c++/7/tuple: In instantiation of ‘constexpr std::_Head_base<_Idx, _Head, false>::_Head_base(_UHead&&) [with _UHead = char [2]; long unsigned int _Idx = 1; _Head = char [2]]’:
