QQmlEngine crash after using clearComponentCache
Unsolved
QML and Qt Quick
-
Hi All,
I'm generating .qml source files on da fly and loading those using Qt.createComponent.
For some reason the created component/object is not up to date no matter if the generated qml source is different/updated since the first load.
I believe it has something to do with caching.If I use the QML Engine's clearComponentCahce things seem to work ok, until shutdown.
I have a crash of the engine.0 org.qt-project.QtQml 0x000000011073cb3d QVector<QFlagPointer<QQmlPropertyCache> >::reallocData(int, int, QFlags<QArrayData::AllocationOption>) + 125 1 org.qt-project.QtQml 0x0000000110739e69 QV4::CompiledData::CompilationUnit::unlink() + 249 2 org.qt-project.QtQml 0x00000001107f5799 QV4::ExecutionEngine::~ExecutionEngine() + 377 3 org.qt-project.QtQml 0x000000011094d320 QV8Engine::~QV8Engine() + 176 4 org.qt-project.QtQml 0x000000011094d42e QV8Engine::~QV8Engine() + 14 5 org.qt-project.QtQml 0x00000001107a2dcf QJSEngine::~QJSEngine() + 79 6 org.qt-project.QtQml 0x00000001108a9dad QQmlEngine::~QQmlEngine() + 381 7 org.qt-project.QtQml 0x00000001108a9dfe QQmlEngine::~QQmlEngine() + 14 8 org.qt-project.QtCore 0x0000000110ddcc03 QObjectPrivate::deleteChildren() + 227 9 org.qt-project.QtWidgets 0x000000011166fc65 QWidget::~QWidget() + 1045 10 org.qt-project.QtQuickWidgets 0x000000011036c8d7 QQuickWidget::~QQuickWidget() + 135 11 com.yourcompany.MaxDesigner 0x000000010fb95da4 MainWindow::~MainWindow() + 116 (mainwindow.cpp:2210)Anyone has seen the same?

I'm seeing the same thing on Qt 5.9.1 on Linux gcc.
