Fatal signal 11 (SIGSEGV)

cocos2d-x C++
1

Hi,

I have this error randomly:
Fatal signal 11 (SIGSEGV) at 0x59f82000 (code=1), thread 30894 (Thread-2921)

I use this command for more info:
adb logcat | /path_to/android-ndk-r9d/ndk-stack -sym obj/local/armeabi

And I have this error:

********** Crash dump: **********

Can anyone help me?
Thank you!

Maybe is a memory problem?

what version of cocos2d-x? What OS?

The version is 3.3 and only happens on Android. On iOS works perfectly.

I use calls to an webservice with HttpRequest, something like this:

void APIManager::getRoutes(int state_id){
    
    loadingModal = LoadingModal::create(getRootNode());
    
    cocos2d::network::HttpRequest* request = new cocos2d::network::HttpRequest();
    request->setUrl(ROUTES_API.c_str());
    request->setRequestType(cocos2d::network::HttpRequest::Type::POST);
    request->setResponseCallback(CC_CALLBACK_2(APIManager::onHttpRequestCompleted, this));
    
    // write the post data
    std::stringstream postData;
    postData << "state_id=" << state_id;
    request->setRequestData(postData.str().c_str(), postData.str().length());
    
    request->setTag("routes");
    cocos2d::network::HttpClient::getInstance()->send(request);
    request->release();
}


void APIManager::onHttpRequestCompleted(HttpClient *sender, HttpResponse *response)
{
    
    loadingModal->dismissModalCallback();
    
    if (!response || !response->isSucceed())
    {
        this->onHttpRequestError("Connection error");
        return;
    }
    
    std::vector<char> *buffer = response->getResponseData();
    std::string strC(buffer->begin(), buffer->end());
    
    rapidjson::Document jsonResponse;
    jsonResponse.Parse<0>(strC.c_str());
    
    if (jsonResponse.HasParseError())
    {
        this->onHttpRequestError("Connection error.");
        return;
    }
    
    if(jsonResponse.IsObject() && jsonResponse.HasMember("error_code")){
        this->onHttpRequestError("Connection error.");
        return;
    }
    else if(jsonResponse.IsObject() || jsonResponse.IsArray()){
        // correct
        _eventCallback(EventType::ON_SUCCESS, strC.c_str());
    }
    else{        
        this->onHttpRequestError("Connection error.");
        return;
    }
}

“loadingModal” is a Sprite with a LoadingBar.

I suspect that the HttpRequest doesn’t close and causes a memory leak. Is possible?

Thank you very much!

Maybe do I need to instance HttpRequest once when app starts and destroy when app ends?
Now, I call:

cocos2d::network::HttpRequest* request = new cocos2d::network::HttpRequest();

on every APIManager method where I do a request to the webservice.

Thank you.
