Warning:Using QCharRef with an index pointing outside the valid range of a QString. The corresponding behavior is deprecated, and will be changed in a future version of Qt.

I have a class derived from QPushButton, I am connecting the clicked signal to a slot in script:

        cnSignal = QObject::connect(this

                ,&clsQtPushBtn::clicked

                ,[pobjScriptEng, strCall, strScript]() {

                              QString strScriptWithCall(strScript + strCall + "();");

                              pobjScriptEng->evaluate(strScriptWithCall);

                );

 

When I click the button the first time everything is ok, however reliably on the second click I see:

     Warning:Using QCharRef with an index pointing outside the valid range of a QString. The corresponding behavior is deprecated, and will be changed in a future version of Qt.

 

In the Application Output.  The scripted slot contains nothing more than:

        function clicked() 

{             console.info("-----clicked()-----");                       }
