Setting macos style before creating a QApplication crashes

On macOS when setting the style as recommended in the documentation before creating a new `QApplication` object, everything works fine for the non macOS styles however when setting the macOS one, the application crashes. Even if there's no need to do that, a crash should not happen anyway since it should be the equivalent of a "noop".

#include <QApplication>
#include <QDebug>int main(int argc, char **argv)
{
    QApplication::setStyle("macos");
    QApplication app(argc, argv);
    app.exec();
}
