I had find out the part that causing the problem . But I still don't know
why it occurs .. Logically , it should be okay . Here is a program that I
extracted out and modified , please discuss with me ...
************************************************************
# include <stdlib.h>
typedef struct ListType {
 int       item;
 struct ListType *link;
}Node;
typedef Node *List;

int main()
{
 List temp;

 temp = (List)malloc (sizeof(List));
 temp->link = NULL;
 free(temp);
 return (0);
}
************************************************************
I think the causing problem is the malloc statement . If I change the malloc
statement into this "temp = (List)malloc (sizeof(Node))" , then when come to
the "free(temp)" it will works as what I expect it to work . Anyone can
explain the side effect of using the List instead of Node ? The problem is ,
even if I use List , the program will still execute as I expect after I
choose Ignore in the Error Message Box that pop up during execution of the
"free(temp)" statement .

/*********ERROR Message box***********/
