在共享内存中查找数组的最小索引时出现问题

#include <stdatomic.h>

void find_min_index_atomic(int* array, int size, atomic_int* min_index) {
    atomic_init(min_index, 0);
    for (int i = 1; i < size; i++) {
        int current_min;
        do {
            current_min = atomic_load(min_index);
        } while (array[i] < array[current_min] && !atomic_compare_exchange_weak(min_index, &current_min, i));
    }
}

#include <vector>
#include <algorithm>
#include <shared_mutex>

public:
    void add_element(int value) {
        std::unique_lock lock(mutex_);
        array_.push_back(value);
    }

    int find_min_index() {
        std::shared_lock lock(mutex_);
        auto min_it = std::min_element(array_.begin(), array_.end());
        return std::distance(array_.begin(), min_it);
    }
