[Insight-developers] ImageConstIterator complaining about non-sensical region boundary violation?

[Williams, Norman K]

Having a problem with the itkTestDriver infrastructure.  We are using ITK4 at the Beta 01 tag.

After our test successfully completes, the Test Driver tries to check two files, but itk::Testing::ComparisonImageFilter is throwing an exception with this message:

BRAINSFitTestDriver: .../ITKv4/Modules/Core/Common/include/itkImageConstIterator.h:177: itk::ImageConstIterator<TImage>::ImageConstIterator(const TImage*, const typename TImage::RegionType&) [with TImage = itk::Image<double, 6u>]: Assertion `Region ImageRegion (0x7fffffffc150)
Dimension: 6
Index: [1, 1, 1, 1, 0, 0]
Size: [115, 107, 101, 1, 1, 1]
is outside of buffered region ImageRegion (0x208d298)
Dimension: 6
Index: [0, 0, 0, 0, 0, 0]
Size: [117, 109, 103, 1, 1, 1]
' failed.

That's wrong.  If I look at the code in itkImageConstIterator.h:

175: const RegionType & bufferedRegion = m_Image->GetBufferedRegion();
176: itkAssertOrThrowMacro( ( bufferedRegion.IsInside(m_Region) ),
177: "Region " << m_Region << " is outside of buffered region " << bufferedRegion );

Something just aint right.
