Subject: [PATCH] QRM: allocate UI on the heap
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

MainWindow has ModelFactory as a member, and that again has large arrays
as members. The stack on Windows cannot handle that, and the test fails
to start.

Allocate the UI on the heap.

Pick-to: 6.10 6.10.0
