[Insight-users] Bug in tiff reader with ReleaseDataFlagOn() ? (ITK 3.14.0)

[Ola Kristoffer Øye]

Hi,
I get a crash (access violation) when setting ReleaseDataFlagOn() on a 
tiff reader in ITK, executing the pipeline, and then calling update on 
the reader. 
It could be that I am using the pipeline in some unintended way, 
otherwise I believe it is a bug.

Platform: Win XP 32, VS 2005, ITK 3.14.0.

Below is a basic example that reproduce the problem: a pipeline that 
reads and writes a tiff image, where the reader has ReleaseDataFlagOn():

#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"

void main(int argc, char* argv)
{
  typedef unsigned short PixelType;
  typedef itk::Image<PixelType, 2> ImageType;
  typedef itk::ImageFileReader<ImageType> Reader;
  typedef itk::ImageFileWriter<ImageType> Writer;

  Reader::Pointer reader = Reader::New();
  Writer::Pointer writer = Writer::New();

  reader->ReleaseDataFlagOn();  //this seems to be the problem
  writer->SetInput(reader->GetOutput());

  reader->SetFileName("C:\\test\\input.tif");
  writer->SetFileName("C:\\test\\output.tif");

  writer->Write();

  reader->Update();  //this triggers a crash }


The crash occurs somewhere inside the tiff reader (stack trace below). 
The file is however successfully written.
Replacing with writer->Update() produces the same crash.

Without ReleaseDataFlagOn(), it works. 
It also works when using a jpg image instead of a tif, even with 
ReleaseDataFlagOn().

I found a similar report from 2004:
