I then hacked and debugged the code for a little bit. I don't see anything wrong with it. Based on you experiment of mixing optimization levels and what I observed, I would tend to agree that there is likely some kind of gcc bug, perhaps in intra-unit optimization or how the data get laid out in certain circumstances.</div><div><br></div><div>The most interesting things I was able to do it the following change:</div><div><br></div><div><div>diff --git a/Modules/Core/Transform/include/itkScalableAffineTransform.h b/Modules/Core/Transform/i</div><div>index 6032127..8dbcdc4 100644</div><div>--- a/Modules/Core/Transform/include/itkScalableAffineTransform.h</div><div>+++ b/Modules/Core/Transform/include/itkScalableAffineTransform.h</div><div>@@ -166,7 +166,7 @@ private:</div><div> const Self & operator=(const Self &);</div><div> </div><div> double m_Scale[NDimensions];</div><div>- InputVectorType m_MatrixScale;</div><div>+ InputVectorType m_MatrixScale __attribute__ ((aligned) );</div><div> }; //class ScalableAffineTransform</div><div> } // namespace itk</div></div><div><br></div><div><br></div><div>With this change all tests pass. Which is _really_ good to know! This mean that all these failing tests are related to this same bug. So I think I have taken this as far as it needs to... I guess I hope that a patch in gcc 4.7 will address this issue.</div><div><br></div><div><br></div><div>On another note. Have you looking at the SimpleITK project? Have you considered also packaging that for Debian distributions?</div><div><br></div><div>Thanks,</div><div>Brad</div><div><br></div><div><br></div><div><br><div><div>On Jun 10, 2012, at 1:41 AM, Steve M.
