            Bug ID: 113595
           Summary: Confusing 'goto' is not a constant expression error
                    message in constructor at compile time
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

  Target Milestone: ---

template<int N>
struct MyArr {
  constexpr MyArr(const int (&arr)[N]) {
    for (int i = 0; i < N; i++)
      arr_[i] = arr[i];
  }
  int arr_[N];
};

constexpr int arr[10] = {};
constexpr MyArr<10> my_arr(arr);

---------------

GCC correctly (I think) rejects the above code, but the error message is a bit
confusing:

<source>:4:5: error: 'goto' is not a constant expression
    4 |     for (int i = 0; i < N; i++)
      |     ^~~

since there is no 'goto' in the code.
