The following script should show a concentric distance map, but a very high value is shown spuriously on it.

In vtkImageEuclideanDistance, the default MaximumDistance is VTK_INT_MAX. The spurious parts keep the value unprocessed. Though I couldn't understand the algorithm, I found suspect lines in vtkImageEuclideanDistance.cxx : b=(int)(floor)((((buff[idx0]-buffer)/spacing)-1)/2);

The variables buff[idx0] and buffer seem to be set squared distances. It's strange to divide only once by spacing. Moreover, if one of these variables was VTK_INT_MAX and spacing<<1, the result would overflow.
