What's wrong with these pointer initialization

int v = 5;    // Store the value 5 in a normal variable
int *n = &v;  // Make n contain the address of v, so that it points to the 
              // contents of v

struct rectangle *create_rectangle(struct point ul, struct point lr,
                                   char *label) {

    struct rectangle *r = malloc(sizeof(struct rectangle));


    r->upperleft=ul;
    r->lowerright=lr;
    strncpy(r->label,label,NAMESIZE);
    r->label[NAMESIZE] = '\0';

    return r;
}
