[Insight-developers] Fwd: [ITK 0012186]: itkBSplineDeformableTransform throws error when enabling multithreading

[Wes Turner]

Nick,

Sorry for the delay.  I'm working under a heavy deadline on something else.

Karthik and I have a test driver that we are working with.  One of us will
take a crack at sending you code and test data that exhibit the failure some
time today (we need to sanitize a few things), but basically it just
required the pipeline:

itkImageFileReader()
... pull out image points into point set
itkBSplineScatteredDataPointSetToImageFilter()
- Spline order 3
- Levels 2
- Number of ctrl points large ... say 50% of the x and y extents of the data

On update of the BSplineFilter, the aforementioned exception is thrown.

- Wes
