Crash on exit because of QQmlApplicationEngine

    XMLWordPrintable

Details

    Description

      When application exits, QQmlApplicationEngine destruction leads to early QQmlContext deletion. If a signal connected to a slot of a QML component is emitted during destruction of other objects, it causes a crash.

      A test application is in the attachment.
