我用的是Microsoft Visual Studio 2008编写的。就是程序用了一次，回到主菜单第二次用就会出现问题 提示如下
Windows has triggered a breakpoint in 22222.exe.

This may be due to a corruption of the heap, which indicates a bug in 22222.exe or any of the DLLs it has loaded.

This may also be due to the user pressing F12 while 22222.exe has focus.

The output window may have more diagnostic information.

用C++ 6.0则提示：
user breakpoint called from code at

[赵4老师]

在每个scanf前面加fflush(stdin);

[xiangyang891006]

还是有问题。麻烦再看下~~~

[skyworth98]

貌似有什么地方有堆破环，多次free，还是缓冲区越界？

[xiangyang891006]

上面的大侠。这是干什么、。本人很急。。。谢谢

[xiangyang891006]

怎么我的编译器没有错误呢？？ Microsoft Visual Studio 2008

[WEBCONFIG]

很诡异啊，我调试了一下。有的时候报错，有的时候不报错。

[xiangyang891006]

是啊。我也很闷啊 啊

[WEBCONFIG]

好像是Initlist这个函数中的问题。

[xiangyang891006]

可以帮我改下吗？谢谢

[WEBCONFIG]

刚才还偶尔报错，现在彻底不报错了。
不好意思，彻底没辙了。

[jvs]

?经典的学生管理系统，用链表写的……慢慢改，花时间

[xiangyang891006]

晕啊晕啊晕。有些电脑上运行时很正常的，就是我的电脑不行~~

[小楫轻舟]

刚调试了下，发现是main函数中malloc处报错，
还没查出原因，要下班了，抱歉，等高手。。。

			while(i<total)
			{
				StudentRecord record;
				InitRecord(record);
				Node *node = NULL; //初始化
				node=(Node*)malloc(sizeof(Node));  //  此处
				InitNode(node);
				SetNode1(node,record,i);
				InsLast(list,node);
				i++;
			}

[xiangyang891006]

恩。我看了也是说这个地方。；可是不知道为什么

[yjjgg]

请问16楼的问题解决没 怎么弄啊 我最近也遇到这个问题
