Description
Application uses QML. After updating QT to 5.7 application start crashing, if you close application.
Call stack -
I found crash. If you use
QQmlContext* tableContext = m_table->rootContext(); tableContext->setContextProperty("MyWidget", this);
Before closing part that depend on QML-Model-View, you have to do it:
QQmlContext* tableContext = m_table->rootContext();
tableContext->setContextProperty("MyWidget", nullptr);
It like reset pointer to nullptr for QML.
QT 5.6 does not have this problem.
