[vtk-developers] Strange memory leaks with vtkImageReslice

[Mathieu Coursolle]

Hi,

I am currently using vtkImageReslice class and am experiencing
some strange memory leaks. 

If I execute this code, I have leaks only is I call SetInformationInput, 
otherwise everything is fine. I looked in vtkImageReslice from what I 
understood that image data is only use to read some parameters.

Does anyone understand what is happening here? 

Thanks!

Here is my code:

int main(int argc, char *argv[])
{	
	vtkImageData* image = vtkImageData::New();
	vtkImageReslice* slicer = vtkImageReslice::New();
	
 slicer->SetInput(image);
	slicer->SetInformationInput(image);    <<< This line causes the leak!!!
	
 image->Delete();
	slicer->Delete();
	
 return 0;
}

This is the console output if the SetInformationInput call is done:

vtkDebugLeaks has detected LEAKS!

Class "vtkInformationVector" has 3 instances still around.

Thanks a lot!
