Judger Internal Error

Traceback (most recent call last):
  File "/app/luogu-judger/source/tasks/Compile.py", line 60, in compile
    enable_o2=enable_o2)
  File "/app/luogu-judger/source/compiler/Compiler.py", line 69, in compile

  File "/app/luogu-judger/source/executor/LrunExecutor.py", line 61, in execute
    raise RuntimeError("Unexpected lrun failure with exit code " + str(ret))
RuntimeError: Unexpected lrun failure with exit code 13

看不懂是什么错 代码：

#include<iostream>
#include<cstdio>
using namespace std;
int a[10],b[50],ans;
int main()
{
	for(int i=0;i<10;i++)
	{
		cin>>a[i];
		b[a[i]%42]++;
	}
	for(int i=0;i<42;i++)
	if(b[i]!=0)
	ans++;
	cout<<ans;
	return 0;
 } 

求大佬指错
