so文件夹：
-bash-3.2$ ls -l so
total 0
-rw-r--r-- 1 bill bill 0 Apr 10 18:30 fileiiiiiiiiiiiiii
执行程序：
-bash-3.2$ ./a.out
link sole4
5
Segmentation Fault (core dumped)
-bash-3.2$
我就想问程序到cout<<""5""<<fileInfoSole.Name<<endl;个语句是报段错误，我猜测是系统调用导致的内存泄露，于是我在程序
FileInfoSole fileInfoSole;和struct dirent entry; 之间放了一个int solearr[200];
数组，就不会出现段错误了或者把so文件夹下的文件fileiiiiiiiiiiiiii改成短一点的file的时就不会出现段错误了，请问这是什么原因导致的，有什么更好的办法解决这个问题，越详细细越好，等代大神解决.....
