c++ - 正在释放的 C++ 指针未分配并在调试期间显示向量的内容

Question

我正在创建一个整数向量来存储一些值。但是，下面的代码似乎根本没有更新向量。错误信息：

malloc: *** error for object 0x200000001: pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug

代码：

#include <vector>
#include <iostream>

#include "Q122.h"

void Q122::solve() {
    std::vector<int> count(200, 0);
    std::vector<std::vector<std::vector<int> > > wholelist(200);
    count[0] = 0;
    std::vector<int> one;
    one.push_back(1);
    wholelist[0].push_back(one);
    int totalsum = 0;
    int index = 0;
    while(index != 199) {
        int currentstep = count[index];
        int currentpower = index+1;
        std::vector<std::vector<int> > list = wholelist[index];
        for(std::vector<int> each : list) {
            for(int number : each) {
                std::vector<int> copied(each);
                int nextindex = number + currentpower - 1;
                copied.push_back(nextindex + 1);
                if(count[nextindex] == 0) {
                    count[nextindex] = currentstep + 1;
                    wholelist[nextindex].push_back(copied);
                    continue;
                }
                if(count[nextindex] != 0 && count[nextindex] > currentstep + 1) {
                    count[nextindex] = currentstep + 1;
                    wholelist[nextindex].clear();
                    wholelist[nextindex].push_back(copied);
                    continue;
                }
                if(count[nextindex] == currentstep + 1) {
                    wholelist[nextindex].push_back(copied);
                    continue;
                }
            }
        }
        std::cout << count[index] << std::endl;
        index++;
        
    }

    int sum = 0;
    for(int each : count)
        sum += each;
    std::cout << sum << std::endl;
}

这个错误信息是什么意思？顺便说一句，如何检查向量的内容？我在 netbeans Mac OS 上使用 clang。

解决了。

问题已解决：我忘了检查 nextindex 的边界。
