QtWebEngine crash only Release

lerxt

Hello,

I am currently experiencing an application crash with a SEGFAULT when trying to use the C++ version of QtWebEngine.
The target device is armhf, running Debian. The Qt version being used is 5.15.13 LTS, and it is being linked statically.

With a Debug configuration, when calling QWebEngineView::load(QUrl), the application functions as expected. However, when building for a Release configuration, the application crashes. This happens with all webpages.

I have experimented with this by creating a separate QWebEnginePage object to then inject it into the QWebEngineView object, however, this also produces a crash only on the Release configuration, and not on the Debug configuration.

A fragment of the code is as follows:

class BrowserScreen {
    public:

    BrowserScreen() = default;
    virtual ~BrowserScreen() = default;

    public slots:
    void FinishLoading(const std::string& url);

    private:
    QWebEngineView* view_;
}

void BrowserScreen::OnURLReceived(const std::string& url) {
    if (!view_) {
        view_ = new QWebEngineView(this);
        QWebEnginePage* page = new QWebEnginePage(this);

        if (page) {
            view_->setPage(page);   // code crashes here
        }
        connect(view_, &QWebEngineView::loadFinished, this, &BrowserScreen::FinishLoading);
    }
    view_->load(QUrl(QString::fromStdString(url)));
}

Operating system: Linux (Debian 12 Bookworm)
