Linux下和core说再见之：栈溢出(2)

两个信息：
1）Program terminated with signal 11, Segmentation fault.
Signal 11, or officially know as "segmentation fault", means that theprogram accessed a memory location that was not assigned. That'susually a bug in the program.

2) core在 cout << "stack  " << group << endl;
在栈溢出的时候，并不一定会马上core，这也是为啥你core的地方常常离出问题的代码很远。

4. 解决

1）在需要占用大内存的时候（例如，大数组），别偷懒，乖乖的用堆！
2）尽量避免层次多的递归函数
