[Qt-creator] Infinite Memory Consumption / QListView (QAbstractItemView), QLineEdit, ...

[Thomas Hartmann]

I encounter an growing, infinite memory consumption in many Qt Construcotrs:

When instantiating objects of type QListView or other, derived from
QAbstractItemView execution does not return from the constructor. Top shows a
rapid growing memory consumption until finally the complete system does not
respond any more.

Same applies to the use of QLineEdit.

This does NOT happen if I don't create an QApplication object ;)

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    //QListView TreeWidget;  // Infinite memory consumption..

    QListView* TreeWidget = new QListView();  // Infinite memory consumption..

    // Execution never comes here

    delete TreeWidget;
    return a.exec();
}
