使用uart_async_rxtxtasks例程，添加打印后会出现stack overflow

[june111]

硬件：ESP32-S3-WROOM-1
软件版本：V5.2.3
开发环境:VS Code
修改的代码如下

Code: [Select all] [Expand/Collapse]

1. static void rx_task(void *arg)
2. {
3.     static const char *RX_TASK_TAG = "RX_TASK";
4.     esp_log_level_set(RX_TASK_TAG, ESP_LOG_INFO);
5.     uint8_t* data = (uint8_t*) malloc(RX_BUF_SIZE + 1);
6.     //uint32_t userFree = 0;
7.     volatile int32_t userFree = 0;
8.     userFree = (int32_t)uxTaskGetStackHighWaterMark(NULL);
9.     ESP_LOGW(RX_TASK_TAG, "111:%d", 0);
10.     userFree = (int32_t)uxTaskGetStackHighWaterMark(NULL);
11.     ESP_LOGI(RX_TASK_TAG, "start is %ld", (int32_t)uxTaskGetStackHighWaterMark(NULL));
12.     userFree = (int32_t)uxTaskGetStackHighWaterMark(NULL);
13.  
14.     while (1) {
15.         ESP_LOGI(RX_TASK_TAG, "min free stack size is %ld", (int32_t)uxTaskGetStackHighWaterMark(NULL));
16.         userFree = (int32_t)uxTaskGetStackHighWaterMark(NULL);    
17.         const int rxBytes = uart_read_bytes(UART_NUM_1, data, RX_BUF_SIZE, 1000 / portTICK_PERIOD_MS);
18.         if (rxBytes > 0) {
19.             data[rxBytes] = 0;
20.             //userFree = uxTaskGetStackHighWaterMark(NULL);
21.             ESP_LOGI(RX_TASK_TAG, "Read %d bytes: '%s'", rxBytes, data);
22.             ESP_LOG_BUFFER_HEXDUMP(RX_TASK_TAG, data, rxBytes, ESP_LOG_INFO);
23.         }

疑问：
1、ESP_LOGW函数调用之后没有释放栈内存？
调用了一次ESP_LOGW(RX_TASK_TAG, "111:%d", 0);之后，后继查看uxTaskGetStackHighWaterMark(NULL)没有变回原来的大小。
2、是否不应该使用uxTaskGetStackHighWaterMark查看，但没有找到获取当前线程剩余栈空间大小的函数接口
