接收到 MQTT 数据后, 出现内存泄漏

发现无法释放 cjson 空间
int raw_resp_ok (mqtt_broker_handle_t *mqtt_broker, int timestamp)
{

char ackmsg[128] = {0}; 
memset (ackmsg,  0x00,  sizeof (ackmsg) ) ; 

char *cjson_str = NULL; 
cJSON *root = NULL; 
cJSON *result = NULL; 

if  ( (root = cJSON_CreateObject () )  == NULL) 
{
    return WM_FAILED; 
}
if  ( (result = cJSON_CreateObject () )  == NULL) 
{
    cJSON_Delete (root) ; 
    return WM_FAILED; 
}

cJSON_AddNumberToObject (root,  "id",  timestamp) ; 
cJSON_AddStringToObject (root,  "result",  "ok") ; 
cjson_str = cJSON_PrintUnformatted (root) ; 

memcpy (ackmsg,  cjson_str,  strlen (cjson_str) ) ; 
if  (mqtt_broker ! = NULL) 
    mqtt_publish (mqtt_broker,   (const char *) MQTT_DEMO_RX_PUB_TOPIC,   (const char *) ackmsg,  strlen (ackmsg) ,  0) ; 
else
    udp_socket_send (light_param_t. dts_ip,  light_param_t. dts_prot,   (uint8_t *) &ackmsg[0],  strlen (cjson_str) ) ; 

if  (cjson_str) 
    free (cjson_str) ; 
// if  (result) 
//     cJSON_Delete (result) ; 
if  (root) 
    cJSON_Delete (root) ; 

return WM_SUCCESS; 

}

能帮忙解决么, json 创建也释放了, 就打开这个函数出现的问题, 我也注释过 mqtt 回复和 udp 回复数据, 也是会出现卡死程序

@Alwp 这个代码里有两个问题, 1, result 没有释放; 2, 内存释放用的是 tls_mem_free, 不是 free;
