[Insight-users] ResampleImageFilter crashes in release mode

[Luis Ibanez]

Hi Michael,

Thanks for reducing the problem to a minimal
example and posting it to the list.

I have build your code under Linux (Ubuntu)
and ran Valgrind on it.

Found that you were not initializing the pixel
data of the memory buffers passed to the
Import filter, and fixed that.

Also fixed an assignment between smart
pointers that was not compiling under gcc

 TransformType::ConstPointer cversor = iversor;

was replaced with:

 TransformType::ConstPointer cversor = iversor.GetPointer();


although a better solution is to change the API of
your "transformImage" method to take const raw
pointers instead of SmartPointer. (the code was
modified accordingly).

The code runs under Linux, both under Release and
Debug without crashing.

Please find the modified code attached.

(Note that, I put the boolean flag of the import filter
to "true", temporarily, in order to avoid a memory
leak report in Valgrind. You probably want to
put it back to "false" in your code).

Also, note that you will need to copy in the same
directory as the main.cxx, the file:

   Insight/Testing/Code/BasicFilters/itkFilterWatcher.h

This is just to capture progress events.


Please try the attached code and let us know
if that makes any difference when you run it
in your Windows system.



      Regards,


           Luis
