One further item.  Of the three files that make up
ITKIOSpatialObjectsTestDriver, as long as this one
is built with -O2:

        itkPolygonGroupSpatialObjectXMLFileTest.cxx.o

I can build the other two with -O3:

        ITKIOSpatialObjectsTestDriver.cxx.o
        itkReadWriteSpatialObjectTest.cxx.o

and the test completes successfully.  This makes no sense to me
because itkPolygonGroupSpatialObjectXMLFileTest code is not even
executed when running the test in question ("ctest -R
itkReadWriteSpatialObjectTest").
