Second Example of 'Getting Started with Qt' Crashes on exit

http://qt-project.org/doc/qt-5.0/gettingstartedqt.html

If you take the second example and fix the includes for qt5 then it will crash on exit as below:

Program received signal SIGABRT, Aborted.

1404 delete d->layout;

The problem is that the layout is deleted but it was allocated on the stack. The same issue can be reproduced under 4.7.4.
