Warning: "implicit copy constructor for 'QListSpecialMethods<QList<int>>' is deprecated"

SeDi

Hi,

QVector<int> v;
QVector<int> w;
v = w;

leads to the warning:
Definition of implicit copy constructor for 'QListSpecialMethods<QList<int>>' is deprecated because it has a user-declared destructor

Am I doing sth wrong?
If not: how can I suppress the warning? I've tried

#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-copy-with-dtor"
QVector<int> v;
QVector<int> w;
v = w;
#pragma clang diagnostic pop

But the warning stays.

I am using Qt6.6.1 MinGW 64 bit on a Windows 10 Pro machine under Qt Creator 10.0.2.

Hi, I have Qt 6.6.3 MinGW 81.0 64-bit on a Windows 10 Pro using Qt Creator 13.0.2.
I started an empty Widgets project and added your 3 lines to the ctor in mainwindow.cpp:

#include "mainwindow.h"
#include "./ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QVector<int> v;
    QVector<int> w;
    v = w;
}

MainWindow::~MainWindow()
{
    delete ui;
}

However it compiles fine, no errors.

Thanks! With upgrading to Qt 6.7.2 the warning vanished.
