[Insight-users] Issues with IO Examples

[Agnes Masson-Sibut]

Hello everybody,

I am a new user of the Insight Toolkit, and I have issues to simply read and
write an image. When I try to execute the exemple ImageReadWrite, I get an
error inside the CreateImageIO function from itkImageIOFactory file :

ImageIOBase::Pointer
ImageIOFactory::CreateImageIO(const char* path, FileModeType mode)
{

  RegisterBuiltInFactories();

  std::list<ImageIOBase::Pointer> possibleImageIO;
  std::list<LightObject::Pointer> allobjects =
    ObjectFactoryBase::CreateAllInstance("itkImageIOBase");
  for(std::list<LightObject::Pointer>::iterator i = allobjects.begin();
      i != allobjects.end(); ++i)
    {
    ImageIOBase* io = dynamic_cast<ImageIOBase*>(i->GetPointer());
    if(io)
      {
      possibleImageIO.push_back(io);
      }
    else
      {
      std::cerr << "Error ImageIO factory did not return an ImageIOBase: "
                << (*i)->GetNameOfClass()
                << std::endl;
      }
    }
  for(std::list<ImageIOBase::Pointer>::iterator k = possibleImageIO.begin();
      k != possibleImageIO.end(); ++k)
    {
    if( mode == ReadMode )
      {
      if((*k)->CanReadFile(path))
        {
        return *k;
        }
      }
    else if( mode == WriteMode )
      {
      if(/*(*k)->CanWriteFile(path)*/false)
        {
        return *k;
        }

      }
==>    } Here, the list can't be deleted because of a memory issue
  return 0;
}

It seems that the program isn't able to delete the list . Here is the call
list :

I tried with different image types, but the result is the same. Is the bug
known ? Is there something I can do to help the thing working out ?

Thanks a lot,
