Until this row it is ok.<br>

community,<br>
I'm facing a strange ITK behavior.<br>
I wrote this code:<br>
<br>
#include "itkImage.h"<br>
#include "itkImageFileReader.h"<br>
#include "itkImageMaskSpatialObject.h"<br>
<br>
int main( int argc, char **argv )<br>
{<br>
typedef itk::Image<unsigned char,3> ImageType;<br>
typedef itk::ImageFileReader<ImageType> ReaderType;<br>
<br>
typedef itk::ImageMaskSpatialObject<3>
MaskImageType;<br>
typedef MaskImageType::Pointer MaskTypePointer;<br>
<br>
ReaderType::Pointer reader = ReaderType::New();<br>
<br>
reader->SetFileName( argv[1] );<br>
reader->Update();<br>
<br>
MaskTypePointer mask = MaskImageType::New();<br>
mask->SetImage(reader->GetOutput());<br>
<br>
return 0;<br>
}<br>
<br>
and it compiles without error.<br>
When I try to run the executable I get a segmentation error
(core dumped).<br>
What's is wrong?<br>
I'm using ITK 3.20.1 on a 64 bit Linux box.<br>
If needed I can provide the mask image.<br>
<br>
Thanks a lot for your help.<br>
Best regards.<br>
Paolo<br>
