[Insight-users] Segmentation fault with 2.2G data but not with smaller subset

[Bradley Lowekamp]

This looks like the following bug:

http://www.itk.org/Bug/view.php?id=6840

I have been meaning to fix this, I'll start.

In the mean time you should be able to get around this bug, by not  
performing a conversion in the Reader. In this case your file is of  
type unsigned char, but you are reading it as a unsigned short with an  
itk::ImageFileReader<Image<unsigned short, 3> >.  Followed this reader  
by a CastImageFilter or a custom adaptor, should enable you to by pass  
this bug.
