Program crash- unable to detect the issue

[newtoQ_s]

The following code is giving me an issue.

void MainWindow::onDelete()
{
 
        if(ui->tableWidget->selectionModel()->hasSelection()){
 
            QItemSelectionModel *selectionmodel =ui->tableWidget->selectionModel();
            QModelIndexList selected_items= selectionmodel->selectedRows();
            qSort(selected_items);
        }

void MainWindow::onDelete()
{

        if(ui->tableWidget->selectionModel()->hasSelection()){

            QItemSelectionModel *selectionmodel =ui->tableWidget->selectionModel();
            QModelIndexList selected_items= selectionmodel->selectedRows();
            qSort(selected_items);
        }

To copy to clipboard, switch view to plain text mode 

Whenever I run it, the program crashes giving me an error:
Invalid address specified to RtlValidateHeap( 006A0000, 00F4DB90 )

It appears to be trying to delete a node from the code in qlist. I am unable to figure out the error. Any advice would be great.

What do you want to achieve by sorting model indexes?
You are aware that this is only for usage with QMap, right?
