Description
The QMainWindowLayout::restoreState starts a problem that causes a crash in the future.
It starts with resetting a unique_ptr called restoredState:
restoredState.reset(new QMainWindowLayoutState(layoutState));
The layoutState copies the restoredState's data in QMainWindowLayout::setGeometry but the restoredState can have invalid data (for example: dangling pointer).
You can get the demo source here:

To reproduse the crash build and run app above. Then close and run it again.
