[ITK Community] [Insight-developpers] filter update causes libc++abi error

[Thibault Lucidarme]

Dear Matt,
I have successfully tried your answer to my registration problem (using
SetNumberOfRequiredInputs and this->SetInput( 0, fixedImage )  )
However this->GetInput() returns a casual pointer instead of a
SmartPointer. In order to be consistent with the rest of my filters (and
the rest of my program), I have had to cast it like this:

ImageType::Pointer fixedImage = const_cast<ImageType*>( this->GetInput(0)
);

as per mentioned here:
http://www.itk.org/pipermail/insight-users/2008-February/024988.html
Yet, when later on in the code I use

registrator->SetFixedImageRegion( fixedImage->GetLargestPossibleRegion() );

the program ends with a segfault. Somehow the casting does not work and
returns NULL.
Do you have any ideas why that is?


Yours Sincerely

Thibault
