You are returning an invalid QwtScaleDiv object - what is the consequence of a 
lousy QwtScaleDiv interface.

Your code needs to look like this:

QwtScaleDiv ScaleEngine::divideScale (...) const
{
    QwtValueList ticks[QwtScaleDiv::NTickTypes];
    ticks[QwtScaleDiv::MajorTick] << 10 << 25 << 35 << 54 << 63 << 100;
    
    QwtScaleDiv scDiv( ticks[QwtScaleDiv::MajorTick].first(),
        ticks[QwtScaleDiv::MajorTick].last(), ticks );
    return scDiv;
}   

The important thing is not to use the default constructor for your QwtScaleDiv 
object.
