[Reg 6.5.2->6.5.3]Triggering a signal of a singleton using Connections segfaults

    XMLWordPrintable

Details

    Description

      Triggering a signal from a simple singleton like the following:

      // Foo.qml
pragma Singleton
import QtQml

QtObject { signal foo() }

      from `Connections` in a different file:

      // Bar.qml
...
    Button { onClicked: Foo.foo() }

    Connections {
        target: Foo
        function onFoo() { console.log("foo"); }
    }
...

      Crashes the application.

       

      I tested the same QML program with 6.5.2 and it works as expected.
