Hi everyone, 

I am using vtkMarchingCubes from release 4.4 (because vtkDecimate is not included in 5.*, and it alone preserves topology robustly). I am finding that trying to run vtkMarchingCubes on certain volumes causes it to crash. I originally had a fairly large volume, .7mm resolution, 304x512x512, but have cropped it since, and it is no larger than another volume for which vtkMarchingCubes does not crash. 

Can anyone suggest a means of debugging this, with a Python implementation? 

Best regards,
