Description
Here is my code compiled with option -std=c++23, gcc 14.2:
#include "timsort.hpp"
#include <array>
#include <iostream>
#include <tuple>
#include <vector>
int main() {
auto x = std::vector{4, 2, 3, 1};
auto y = std::array{'A', 'C', 'B', 'D'};
auto xy = std::views::zip(x, y);
gfx::timsort(xy, {},
[](const std::tuple<int &, char &> &a) {
return std::get<0>(a);
});
for (std::tuple<int &, char &> elem : xy) {
std::cout << std::get<0>(elem) << ' ' << std::get<1>(elem) << ' ' << '\n';
}
}Expected result is:
1 D
2 C
3 B
4 A
However, I got
4 A
2 C
4 A
4 A
