变量周围的堆栈"variable name"已损坏C++

我有一段代码，应该是大学里一个项目的mips处理器的汇编程序
现在我的问题是，当执行程序时，一切都很顺利，直到程序退出主程序，它会抛出这个错误：

变量CCD_ 1周围的堆栈已损坏。

这个错误是在退出main时抛出的，我在任何地方都找不到有效的解决方案。

下面是我的代码示例：

#include <iostream>
#include <fstream>
#include <string>
#include <bitset>
using namespace std;
//function to convert string to binary
bool tobool(char x)
{
    if (x == '0')
        return 0;
    else
        return 1;
}
//function to decode the register name into an address using call by refrence to modify the instruction boolean encoding array
void register_encode(string Register, bool &address2, bool &address3, bool &address4, bool &address5, bool &address6)
{
    if (Register == "$zero")
    {
        address2 = 0;   address3 = 0;   address4 = 0;   address5 = 0;   address6 = 0;
    }
    else if (Register == "$t3")
    {
        address2 = 0; address3 = 1; address4 = 0; address5 = 1; address6 = 1;
    }
    else if (Register == "$s2")
    {
        address2 = 1; address3 = 0; address4 = 0; address5 = 1; address6 = 0;
    }
}
//function to count the number of occurence of commas (,) inside the string
int count_commas(string s) {
    int count = 0;
    for (int i = 0; i < s.size(); i++)
        if (s[i] == ',') count++;
    return count;
}
void main()
{
    int numberofinstruction = 0;
    string testingstring;
    string line[64];
    ifstream myfile;
    myfile.open("test.txt");
    // taking input from file into an array "line" which holds every single line inside the array in a single element inside the array
    while (getline(myfile, testingstring))
    {
        line[numberofinstruction] = testingstring;
        numberofinstruction++;
    }
    myfile.close();
    //transform to binary
    bool binaryinstruction[31];
    string firstterm, secondterm, thirdterm, fourthterm;
    for (int counter = 0; counter<numberofinstruction; counter++)
    {
        switch (count_commas(line[counter])) {
        case 1:
            firstterm = line[counter].substr(0, line[counter].find(" "));
            secondterm = line[counter].substr(line[counter].find(" ") + 1, line[counter].find(",") - line[counter].find(" ") - 1);
            thirdterm = line[counter].substr(line[counter].find(",") + 1, line[counter].size() - line[counter].find(","));
            if (firstterm == "lw")
            {   //LW encoding
                binaryinstruction[0] = 1;
                binaryinstruction[1] = 0;
                binaryinstruction[2] = 0;

                register_encode(secondterm, binaryinstruction[11], binaryinstruction[12], binaryinstruction[13], binaryinstruction[14], binaryinstruction[15]);
                string offset = thirdterm.substr(0, thirdterm.find('('));
                offset = bitset<16>(stoi(offset)).to_string();
                for (int x = 0; x <= 15; x++)
                {
                    binaryinstruction[16 + x] = tobool(offset[x]);
                }
                string lwregister = thirdterm.substr(thirdterm.find('$'), thirdterm.size() - thirdterm.find('(') - 2);
                register_encode(lwregister, binaryinstruction[6], binaryinstruction[7], binaryinstruction[8], binaryinstruction[9], binaryinstruction[10]);
            }
            else
            {   //SW encoding
                binaryinstruction[0] = 1;
                binaryinstruction[1] = 0;

                for (int x = 0; x <= 15; x++)
                {

                }
                string lwregister = thirdterm.substr(thirdterm.find('$'), thirdterm.size() - thirdterm.find('(') - 2);
                register_encode(lwregister, binaryinstruction[6], binaryinstruction[7], binaryinstruction[8], binaryinstruction[9], binaryinstruction[10]);
                //end
            }
            break;
        }
    }
    //testing
    ofstream myfile2("testout.txt");
    for (int f = 0; f <= 31; f = f + 8)
    {
        myfile2 << binaryinstruction[f] << binaryinstruction[f + 1] << binaryinstruction[f + 2] << binaryinstruction[f + 3] << binaryinstruction[f + 4] << binaryinstruction[f + 5] << binaryinstruction[f + 6] << binaryinstruction[f + 7] << endl;
    }
    //end testing
}

在测试文件中，我有一行是lw $t3,4($s2)，要在测试文件内写入的输出是：

10001110
01001011
00000000
00000100
