我刚刚安装了MPIR库。我测试了程序可以看到空代码中的头文件如下：

#include <iostream>
#include <conio.h>
using namespace std;

#pragma warning(disable: 4800)
#include <mpirxx.h>
#pragma warning(default: 4800)

int main (int argc, char *argv[])
{   
  mpz_class aBigPO2;

  aBigPO2 = 1073741824; //2^30
  aBigPO2*=aBigPO2; //2^60
  aBigPO2*=aBigPO2; //2^120
  aBigPO2*=aBigPO2; //2^240
  aBigPO2*=aBigPO2; //2^480
  aBigPO2*=aBigPO2; //2^960
  aBigPO2*=aBigPO2; //2^1920 
 // cout << aBigPO2 << endl;

cout<<"Hello World";
getch();
}

我尝试编译和调试上面的代码，它运行良好，我可以看到 Hello World 语句。但是，当我删除cout << aBigPO2 << endl;语句中的注释时，仅在调试时出现以下错误（编译时，它不显示任何错误）

尝试为 mpir.h 添加 #include 并查看是否可以修复它。

在 CPP 中，字符串文字的最大长度为 16,384 (16K) 字节。您是否检查过 (2^1920 = 9.49711451 x 10577) 是否在此范围内？
