Description

I'm compiling daily builds of Qt, from stable branch.
This code used to work fr years. Now is crashing in the latest git.

    QFileDialog dialog;

...

    QGridLayout *layout = (QGridLayout*)dialog.layout();
    layout->addLayout(rowLayout,4,0,1,-1);

The backtrack is:

Program received signal SIGSEGV, Segmentation fault.
