C语言：创建链表时，内存申请出错

创建链表中，在申请结点的内存时出现了问题

#include <stdio.h>
#include <string.h>

#define MAXSIZE 20//字符串的最大长度
#define T 3//阈值

typedef struct data_splited {//数据包的数据域
    char* s;
    int length;
    char* p;
}Data_splited;
typedef struct list_splited {//将字符串切分后的数据包
    Data_splited data;
    struct list_splited* next;
}List_Splited;
typedef struct//创建函数返回的类型，其返回的字串最多为20个
{
    char S[10][MAXSIZE];
}Result_split;
