[Insight-developers] cswig segmentation fault

[Bill Hoffman]

I found the problem.   The SegmentationLevelSetImageFilter class did
not provide a protected copy constructor and this caused cswig to crash.
I have modified cswig, so it will print out a message and abort when this
condition occurs.  Something like this: 

Building wrap_itkShapeDetectionLevelSetImageFilterTcl.cxx from  C:\Hoffman\InsightNew-vc\Wrapping\CSwig\Algorithms\wrap_itkShapeDetectionLevelSetImageFilterTcl.cxx.rule
SWIG: Fatal internal error. Constructor with no symname, perhaps the only public constructor is compiler generated, for ITK make sure all constructors are declared protected including the copy constructor. !
Error for itk::SegmentationLevelSetImageFilter<(itk::Image<(float,2)>,itk::Image<(float,2)>,float,itk::Image<(float,2)> )>
SWIG: Fatal internal error. Constructor with no symname, perhaps the only public constructor is compiler generated, for ITK make sure all constructors are declared protected including the copy constructor. !
Error for itk::SegmentationLevelSetImageFilter<(itk::Image<(float,2)>,itk::Image<(float,2)>,float,itk::Image<(float,2)> )>

wrap_itkShapeDetectionLevelSetImageFilterTcl.cxx - 2 error(s), 0 warning(s)



I added the protected copy constructor to the SegmentationLevelSetImageFilter class and it now wraps OK.  
I have also wrapped changed wrap_itkShapeDetectionLevelSetImageFilter.cxx to wrap the parent classes.
