Dear Maintainer, I'm running a (Py)Qt5 application as part of a CI, and once all few days I get a segfault on exit here: .../libQt5Network.so.5(QNetworkConfigurationManagerPrivate::pollEngines() 0xe4)[0x7f262566b9b4] .../libQt5Network.so.5( 0x10f20d)[0x7f26256db20d] .../libQt5Core.so.5(QMetaObject::activate(QObject*, int, int, void**) 0x77d)[0x7f262eb0ffdd] .../libQt5Core.so.5(QTimer::timerEvent(QTimerEvent*) 0x28)[0x7f262eb1da58] .../libQt5Core.so.5(QObject::event(QEvent*) 0xb3)[0x7f262eb10e93] .../libQt5Widgets.so.5(QApplicationPrivate::notify_helper(QObject*, QEvent*) 0x8c)[0x7f262758b12c] .../libQt5Widgets.so.5(QApplication::notify(QObject*, QEvent*) 0x3a0)[0x7f2627590600] .../QtWidgets.cpython-34m-x86_64-linux-gnu.so( 0x15f5b6)[0x7f26267d25b6] .../libQt5Core.so.5(QCoreApplication::notifyInternal(QObject*, QEvent*) 0xdb)[0x7f262eae0dcb] .../libQt5Core.so.5(QTimerInfoList::activateTimers() 0x595)[0x7f262eb38045] .../libQt5Core.so.5( 0x3314c1)[0x7f262eb384c1] .../libglib-2.0.so.0(g_main_context_dispatch 0x24d)[0x7f262daa6c5d] .../libglib-2.0.so.0( 0x49f48)[0x7f262daa6f48] .../libglib-2.0.so.0(g_main_context_iteration 0x2c)[0x7f262daa6ffc] .../libQt5Core.so.5(QEventDispatcherGlib::processEvents(QFlags<QEventLoop::ProcessEventsFlag>) 0x6c)[0x7f262eb391cc] .../libQt5Core.so.5(QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>) 0x112)[0x7f262eade512] .../libQt5Core.so.5(QThread::exec() 0xb4)[0x7f262e89ecb4] .../libQt5Core.so.5( 0x9cd2e)[0x7f262e8a3d2e] .../libpthread.so.0( 0x80a4)[0x7f2632cec0a4] .../libc.so.6(clone 0x6d)[0x7f2631ccd04d] Full catchsegv log: http://qutebrowser.org:8010/builders/debian-jessie/builds/1214/steps/unittests/logs/stdio This has been reported and fixed upstream: https://bugreports.qt.io/browse/QTBUG-44407 https://codereview.qt-project.org/#/c/111893/ And indeed I've not seen this happen since 5.4.2.
