Problem with linked list and strings

[Tom Avens]

#include <stdio.h>    /* for printf */
#include <stdlib.h>   /* for malloc */
#include <string.h>
 
struct node
{
	char *data;
	struct node *next; /* pointer to next element in list */
};
 


struct node *list_add(struct node **p, char *i)
{
	struct node *n = (node *)malloc(sizeof(struct node));
	if (n == NULL)
		return NULL;
 
	n->next = *p; /* the previous element (*p) now becomes the "next" element */
	*p = n;       /* add new empty element to the front (head) of the list */
	n->data = i;
 
	return *p;
}


void list_print(struct node *n)
{
	if (n == NULL)
	{
		printf("list is empty\n");
	}
	while (n != NULL)
	{
		printf("print %s\n", n->data);
		n = n->next;
	}
}
 
int main(void)
{
    
    int i;
    char buf[1024];
    struct node *n = NULL;
 
    for (i=0;i<5;i++){

        gets(buf);
        
        list_add(&n, buf);
     }

	//list_add(&n, "aa"); 
	//list_add(&n, "bb"); 
	//list_add(&n, "cc"); 
	//list_add(&n, "dd"); 
	//list_add(&n, "ee"); 
	list_print(n);
	
	
 
    
	return 0;
	
}

I have this code and it put to all nodes the last input of gets(). However the code in comments(if i don't use gets()) works correctly.

Any idea?
