Nonzero exit code on ITK filter

Question

I am using an ITK BinaryThinningImageFilter3D. However, the code (where mask is an np.uint8 3D Numpy array filled with 0s and 1s - it is a voxel representation of an arthery)

import itk
output = itk.BinaryThinningImageFilter3D.New(
    itk.GetImageFromArray(mask)
)

gives

Process finished with exit code -1073741819 (0xC0000005)

This answer points towards Python version - I checked it, everything is x64. I am leaning towards some kind of data type incompatibility. Any hints on how to fix?

Wrap this in a try...catch block and print the error message. That will tell you what went wrong. Perhaps something like:

try:
  import itk
  output = itk.BinaryThinningImageFilter3D.New(
    itk.GetImageFromArray(mask))
except RuntimeError as e:
  print('Got an exception\n' + str(e))

But that's the point - ITK terminates the program. It never reaches `except` clause. – alex Sep 09 '19 at 14:19
How about `except itk.ExceptionObject as e:`? – Dženan Sep 10 '19 at 15:02
This doesn't work either. Program simply terminates while in the C code part. – alex Sep 10 '19 at 20:34

I turns out there was a segfault. Issue fixed in new version of the library.
