I have a c++ program written in Qt5 5.14.1.
It also use privoxy source code inside.

Each time I click quit, or Command + Q. It will quit and crash.
Is there a way to determine what cause the issue?
Apple Will pop a window when application crash, this is very annoying.

Hey StackOverflow detectives.
I've been pulling my hair out for a few months trying to figure out the crashes which happen at a line never exists.
In the crash log below, CustomClass.swift does exist but the line 25 doesn't.
What would be the true reason for this crash?
Hint: we run heavy processing and allocate a lot of memory (about 700MB) in the background that was written in c++, which is in OUR_CUSTOM_FRAMEWORK below.

I am using Qt 5.7 under MacOS Sierra, and I was experimenting with Qt's GroupedDragging in docks. However, this crashes my app a lot when I'm moving my docks around. It's quite random so I cant reproduce the error.
This is how I set my dock options:
setDockOptions(DockOptions( QMainWindow::GroupedDragging) );
I already tried enabling and disabling animations, tabbedDocks, etc, nothing seems to work.
Is there anything I can do?
This is the stacktrace:

We have an OS X C++ application, using Qt 5.5 that provides a simple HTTP server interface. It's essentially similar to the Fortune Server example provided by Qt (http://doc.qt.io/qt-5/qtnetwork-fortuneserver-example.html), but what we're seeing is that occasionally the application is seg faulting upon shutdown, with the following stack trace (thread 6 crashing):

As you can see, thread 0 is done - we're outside main. I'm sure there's some cleanup code I'm failing to call when we're disposing of our resources, but I don't know what it can be.
Without putting all our source up here, the basic chain of calls were doing is:
class RestServer : public QObject {
RestServer::RestServer() {
_tcpServer = new QTcpServer(this);
}
void RestServer::listen(quint16 port)
{
if (!_tcpServer->listen(QHostAddress::LocalHost, port)) {
LOG_ERROR("RestServer", "Failed to start server at: " << port);
throw std::exception();
}
_portNum = _tcpServer->serverPort();
LOG_INFO("RestServer", "Server is listening at: " << _portNum);
connect(_tcpServer, SIGNAL(newConnection()), this, SLOT(connectSocket()));
}
Then in our test code, we basically do:
void RestAPIServer_test::responseCallback(QNetworkReply *reply)
{
auto response = reply->readAll();
_uri = response;
reply->close();
QCoreApplication::exit();
}
TEST_F(RestAPIServer_test, urlWithPercents)
{
RestServer restServer();
restServer.listen(0);
quint16 port = restServer.serverPort();
// "widget/foo bar.txt"
QUrl serviceUrl(QString("http://localhost:%1/path/?path=widget%2Ffoo%20bar.txt").arg(port));
QNetworkAccessManager networkManager(this);
connect(&networkManager, SIGNAL(finished(QNetworkReply*)), this, SLOT(responseCallback(QNetworkReply*)));
QNetworkRequest request(serviceUrl);
request.setHeader(QNetworkRequest::ContentTypeHeader, "application/x-www-form-urlencoded");
networkManager.get(request);
QCoreApplication::exec();
ASSERT_EQ(QString("path=widget/foo bar.txt"), _uri);
}
It is not safe to instantiate a QObject on stack with a parent. Look at the line
QNetworkAccessManager networkManager(this);
The object would be destroyed twice, which is not possible, so you see the crash. Change that line as follows (of course, the use of variable networkManager must also be updated):
QNetworkAccessManager* networkManager=new QNetworkAccessManager(this);
The problem seemed to be due to some networking-related threads created by Qt still running for a bit after the call to QCoreApplication::quit() was called, probably because the quit() was called from within the callback function registered with the QTcpSocket. The solution was to put a 1-second sleep after the call to exit:
void RestAPIServer_test::responseCallback(QNetworkReply *reply)
{
auto response = reply->readAll();
_uri = response;
reply->close();
QCoreApplication::exit();
// This prevents a shutdown race condition where Qt service
// threads continue to run after the call to exit().
std::this_thread::sleep_for(std::chrono::milliseconds(1000));
}
I knew EXC_BAD_ACCESS & Zombie, and how to find it in normal way. But what I face now is very very confusing, at least to me.
Background
I have a multi-account app, in which the user can login many accounts at the same time.
The app works well with only one account on, but when the user really logins more and more accounts, the app becomes more and more vulnerable as well, crashing randomly but mostly on AppLaunch. Not 8badf00d, but EXC_BAD_ACCESS (SIGSEGV) / KERN_INVALID_ADDRESS.
Code Architecture
Objective-C - Application level, including UI.
|
Objective-C & C++ - Account Context, including login logic.
|
C++ - Net/Communication level, including sockets.
Notification & Delegation are both used between levels.
Reproduce
Double-tap the Home button, swipe the app out to kill it, then tap the app icon to relaunch it. After passing TouchId, the app will login the accounts, and randomly crash, resulting in many different crash logs. No matter the device is iPhone 6s plus or iPhone 5s/5c/5, iOS 8 or iOS 9.
The memory usage is not high, just several tens of MB.

Though I have logs in hand, I still have no idea how to solve it. Maybe the Address Space has been dirty? Forcibly / unintentionally modified by the C++ level?
Thanks in advance.
I'm using wxWidgets, and I have a wxTreeCtrl set up with a root and a single child. I'm setting client data on the child and it works fine until the window closes, at which point I get a bus error, which I'm assuming is coming from wxWidgets attempting to delete my client data.
Here's my client data struct:
struct MapPtrCtr {
Map* map;
MapPtrCtr(Map* map) : map(map) {}
};
Here's how I set the client data (note that here, map is std::shared_ptr<Map>):
wxTreeItemId childNode = mapTree->AppendItem(node, map->getTitle());
mapTree->SetItemData(childNode, (wxTreeItemData*) new MapPtrCtr(map.get()));
Here's the error I get:

Any suggestions? I'm not sure how to properly use wxTreeItemData because there's very little documentation on it. The docs say to make sure to initialize the struct with new, and I do, so I'm not sure why there's a problem.
That was quick. I figured out how to properly use wxTreeItemData: you have to subclass it, not just cast to it. The following client data class works:
class MapPtrCtr : public wxTreeItemData {
public:
Map* map;
MapPtrCtr(Map* map) : map(map) {}
};
