[Dev-C++] System crash happen when I run a very simple linear list' program.

[<per...@ya...>]

I have writed a simple program just only construct two empty linear list.The process of compile is no problem.But after run it,the system crash occur.If I remove the sentence (2),the problem will not come.Can 
anyone tell me how to do If I want to use the function InitList() separate to construct two empty list?
     Thanks,

My program list below:
/*  A simple program that want to construct two empty linear list */
#define LIST_INIT_SIZE   10    
typedef int ARRAY;
typedef struct {
    ARRAY   *elem;   /* a pointer of one dimension array */
    int     length;     /*the linear list current length */ 
    int     listsize;   /* the linear list's space that has distributed */
}LineList;

/* construct a empty linear list */
ARRAY *InitList(LineList *list)
{
    list->elem = (ARRAY *) malloc(LIST_INIT_SIZE * sizeof(ARRAY));
    list->length = 0;
    list->listsize = LIST_INIT_SIZE;
    return list->elem;
}
main()
{
    LineList    *list, *list1;
    
    /* want to create two empty linear list */
    list->elem = InitList(list);   /* sentence (1) */
    list1->elem = InitList(list1);  /* sentence (2) */
    system("PAUSE");
}
