>6000 memory leaks in simple app

A simple Qt application running on Symbian^4 wk34 is reporting over 6000 memory leaks.
This only seems to happen on hardware builds.
It only happens when using latest Qt from the repositories, not the Qt productization branch.

Analysis tools are showing many of the following.
