c++ - 编译C++代码导致系统挂起

Question

当我尝试通过发出命令“g++ qr.cpp -o qr”来编译此文件时，系统挂起。我在其他任何地方都没有看到这种错误。

#include<iostream>

using namespace std;

bool win[1000000001];
bool know[1000000001];

int sixes[] = {6, 36, 216, 1296, 7776, 46656, 279936, 1679616, 10077696, 60466176, 362797056};

bool check(int n){
   cout << n << endl;
   if(!know[n]){
      bool b = check(n-1);
      for(int i=0; i<11; i++){
         if(n > sixes[i]){
            b = b & check(n-sixes[i]);
         }
      }
      win[n] = !b;
   }
   return win[n];
}

int main(){
   win[1] = know[1] = true;
   for(int j=0; j<11; j++){
      win[sixes[j]] = know[sixes[j]] = true;
   }
   int n = 1; 
   cin >> n;
   int i = 0;
   while(n != 0){
      i++;
      win[n] = check(n);
      cout << i << (win[n]?"-Heckle":"-Jeckle");
      cin >> n;
      if(n!=0) cout << endl;
   }
   return 0;
}

我的编译器版本信息如下。

你知道它们有多大吗？

bool win[1000000001];
bool know[1000000001];

每个至少 1GB!你会想要动态分配它们......
