      The following example crashes the application when the qml compiler is used.

      The "workaround" actually disables c++ compilation (reason: "Cannot generate efficient code for StoreElement with non-list base type or non-numeric arguments", whatever that means).

      import QtQuick

Window {
  width: 640
  height: 480
  visible: true
  title: qsTr("Hello World")

  Component.onCompleted: {
    let bar = {};

    // => crash in generated c++ code
    bar["foo"] = 42;

    // => "workaround"
    // const key = "foo";
    // bar[key] = 42;
  }
}
