      Description

      Platform: Embedded Linux Kernel 2.6.37.6-4.0-20140320-S
      Qt version: Qt 5.6.0
      Application: QML GUI app (the client) with backed communication to a server by using QT Network (we use HTTP).
      When the client has not received a reply from the server after a timeout, the client calls QNetworkReply::abort() on the pending request.

      The App crashes randomly (from time to time after having run for a while) as follows:

      [ QCoreApplicationPrivate::sendPostedEvents(QObject*, -> QCoreApplication::notifyInternal2(QObject*, -> QCoreApplication::notify(QObject*, -> QObject::event(QEvent*) -> QHttpThreadDelegate::~QHttpThreadDelegate() -> QNetworkAccessCache::releaseEntry(QByteArray -> QNetworkAccessCache::updateTimer() -> QBasicTimer::start(int, -> QAbstractEventDispatcher::registerTimer(int, -> QAbstractEventDispatcherPrivate::allocateTimerId() ]

      Still working on extracting the exact use case.

      Just wondering if anyone has encountered the same backtrace?

      Any fixes after Qt 5.6.0 in the same area?
