    Description

      Run this (occurs only in "debug"):

      QPrinter printer; //This line crash app
QPrintPreviewDialog preview(&printer);
preview.setWindowFlags(Qt::Window);
QObject::connect(&preview, SIGNAL(paintRequested(QPrinter *)), SLOT(printPreview(QPrinter *)));
preview.exec();

qDebug() << "No crash";

      Crash app and returns:

      Invalid parameter passed to C runtime function.

qDebug() << "No crash";
