GPRS_C_SDK SSL_Connect crash after connecting many times

1. SDK version（SDK 版本）

{ V2.112 }

2. In what kind of operation problems appear, and how to reproduce the problem ?（什么样的操作步骤问题会出现，是否是稳定复现，如何复现问题？）

I have a code that will connect to a server with SSL. After approximate 8 min of connecting to a server, the function SSL_Connect crash giving me a error like the next one on coolwatcher:

Detected event: 0x9db00000 Detected event: 0x9db10000

GDB:

I think is a memory leak. By the release V2.112 in the updates note there is fix ssl reconnect memory leak bug but I think the bug still there.

My code is HERE

And some summary of my code:

     ...
     ...
     ...

//https POST
int Https_Post(const char* domain, const char* port,const char* path, const char* data, uint16_t dataLen, uint8_t* retBuffer, int bufferLen){
    const int bufferSize = 2048;

    int ret;
    SSL_Error_t error;
    SSL_Config_t config = {
        .caCert = ca_cert,
        .caCrl  = NULL,
        .clientCert = NULL,
        .clientKey  = NULL,
        .clientKeyPasswd = NULL,
        .hostName   = domain,
        .minVersion = SSL_VERSION_SSLv3,
        .maxVersion = SSL_VERSION_TLSv1_2,
        .verifyMode = SSL_VERIFY_MODE_OPTIONAL, // SSL_VERIFY_MODE_REQUIRED
        .entropyCustom = "GPRS"
    };

    // Build the package
    char* buffer = OS_Malloc(bufferSize);
    snprintf(buffer, bufferSize, "POST %s HTTP/1.1\r\nHost: %s\r\nContent-Type: application/x-www-form-urlencoded\r\nContent-Length: %d\r\n%s \r\n\r\n", path, domain, (dataLen-2), data);

    char* pData = buffer;
    Trace(1,"#LOG: Package: %s", pData);

    error = SSL_Init(&config);
    if(error != SSL_ERROR_NONE){
        Trace(1,"#LOG: ssl init error:%d",error);
        OS_Free(buffer);
        return -1;
    }
    else{
        // If SSL init, Connect to server
        error = SSL_Connect(&config, domain, port); // BUG HERE: crash after 8min aprox.
        if(error != SSL_ERROR_NONE){
            Trace(1,"#LOG: ssl connect error:%d",error);
            goto exit02;
        }

     ...
     ...
     ...

void SecondTask(void *pData){
    while(1){
            if(Https_Post(SERVER_IP, SERVER_PORT, SERVER_PATH_POST, locationBuffer, strlen(locationBuffer), buffer, bufferSize) < 0){
                Trace(1,"http get fail");
            }
}

     ...
     ...
     ...

// ----------------------------------------- Main task
void MainTask(void *pData){
    API_Event_t* event=NULL;

    // Create another task (secondary task).
    secondTaskHandle = OS_CreateTask(SecondTask,
        NULL, NULL, SECOND_TASK_STACK_SIZE, SECOND_TASK_PRIORITY, 0, 0, SECOND_TASK_NAME);

    while(1){
        // Wait for events from the lower system and is handle in EventDispatch
        if(OS_WaitEvent(mainTaskHandle, (void**)&event, OS_TIME_OUT_WAIT_FOREVER)){
            EventDispatch(event);
            OS_Free(event->pParam1);
            OS_Free(event->pParam2);
            OS_Free(event);
        }
    }
}

// ----------------------------------------- Main entrance
void shoes9G_Main(void){
    // Create the main task. It will return the pointer os that task.
    mainTaskHandle = OS_CreateTask(MainTask,
        NULL, NULL, MAIN_TASK_STACK_SIZE, MAIN_TASK_PRIORITY, 0, 0, MAIN_TASK_NAME);
    OS_SetUserMainHandle(&mainTaskHandle); // Set the main handle.
}

You can reproduce the same problem by compiling this project

Thanks you so much in advance.
