help: esp32c3 - ERROR: using wasm-hexarray twice

[HalfUnitato]

Hey guys,
I try to expand the example for the esp32c3 in: https://github.com/bytecodealliance/wasm-micro-runtime/tree/main/product-mini/platforms/esp-idf/main:

For the WASM_ENABLE_AOT Section, I called wasm_module = wasm_runtime_load twice in a row, with the same parameter.
But using a wasm_file_buf for another load-call results in the following error log-messages:

I (328) wamr: Run wamr with AoT
E (338) wamr: Error in wasm_runtime_load: AOT module load failed: unexpect end
I (348) wamr: Destroy WASM runtime

Is this a bug or a feature?

Thanks in advance

following part of my code and the given log:

unsigned char __aligned(4) wasm_test_file1[] = {
    0x00, 0x61, 0x73,
    ....
    0x74, 0x20, 0x74, 0x61, 0x73, 0x6B, 0x00
};


typedef struct {
    size_t size;
    uint8_t *array;
} array_as_param;

main {
    ...
   # call first time -----------
    array_as_param *param1 =
        (array_as_param *) malloc(sizeof(array_as_param));
    param1->size = sizeof(wasm_test_file1);
    param1->array = (uint8_t *)wasm_test_file1;
    ESP_LOGI(LOG_TAG, ">>>> p1: %p", param1->array);
    ESP_LOGI(LOG_TAG, ">>>> s1: %zu", param1->size);

    run_module((void *)param1);

   # call second time -----------
    array_as_param *param2 =
        (array_as_param *)malloc(sizeof(array_as_param));
    param2->size = sizeof(wasm_test_file1);
    param2->array = (uint8_t *)wasm_test_file1;
    ESP_LOGI(LOG_TAG, ">>>> p2: %p", param2->array);
    ESP_LOGI(LOG_TAG, ">>>> s2: %zu", param2->size);

    run_module((void *)param2);
    ...
}

void *
run_module(void *args)
{
    array_as_param *param = (array_as_param *) args;
    uint8_t *wasm_file_buf = param->array;
    unsigned wasm_file_buf_size = param->size;
    wasm_module_t wasm_module = NULL;
    wasm_module_inst_t wasm_module_inst = NULL;
    char error_buf[128];

    /* load WASM module */
    if (!(wasm_module = wasm_runtime_load(wasm_file_buf, wasm_file_buf_size,
                                          error_buf, sizeof(error_buf)))) {
        ESP_LOGE(LOG_TAG, "Error in wasm_runtime_load: %s", error_buf);
        return 0;
    }
    ...
}

giving:

IMU, after first wasm_runtime_load(), the file(of .wasm) position indicator pointed to the end of file. So the second wasm_runtime_load() thought it is an empty file.

thanks for your reply,
I checked the parameters given to wasm_runtime_load (size and pointer-value and both are for each call the same).

I added code and terminal-log to my original-question
