Summary0012186: itkBSplineDeformableTransform throws error when enabling multithreading
DescriptionWhen enabling multithreading in itk and set the number of threads > 1, the itkBSplineDeformableTransform throws an error saying:

itk::ExceptionObject (0x24efee0)
Location: "void itk::BSplineDeformableTransform<TScalarType, NDimensions, VSplineOrder>::SetParameters(const typename itk::Transform<TScalarType, NDimensions, NDimensions>::ParametersType&) [with TScalarType = double, unsigned int NDimensions = 3u, unsigned int VSplineOrder = 3u]"
File: /scr/morse1/programming/src/ITK/Modules/Core/Transform/include/itkBSplineDeformableTransform.txx
Line: 354
Description: itk::ERROR: BSplineDeformableTransform(0x24efc40): Mismatch between parameters size 19728016 and expected number of parameters 1536

If you set the number of threads to 1 it works perfectly.
I encountered this error with the ITK release 3.20 (review code) as well.

As an ITK object, the B-spline deformable transform does not operate with a specific number of threads.
I suspect that the reporter is referring to some specific application, like image registration, in which the failing occurs. I was able to load a b-spline deformable transform into the itkResampleImageFilter, set the number of threads > 1, and it ran for me just fine. I'm setting this issue resolved until I get more feedback as to the specific cause, hopefully with some code to reproduce the error.
