and those segfaults seems to go back to FFT facilities:

wouldn't it be useful to may be build it in Debug mode by default for now
instead of default Release so failures could be readily troubleshooted? then
it might provide an ITK knowledgeable person (i.e. not me) clues, such as:
PlanRigor: FFTW_EXHAUSTIVE (8)
ITKFFTTestDriver: /tmp/buildd/insighttoolkit4-4.1.0/Modules/Filtering/FFT/include/itkFFTWCommon.h:247: static fftwf_plan_s* itk::fftw::Proxy<float>::Plan_dft_r2c(int, const int*, itk::fftw::Proxy<float>::PixelType*, float (*)[2], unsigned int, int, bool): Assertion `plan != __null' failed.
Aborted
Happens on the 2nd invocation of
Breakpoint 1, itk::fftw::Proxy<float>::Plan_dft_r2c (rank=1, n=0x86f75a0, in=0x86f9758, out=0x86f8028, flags=24, threads=8, canDestroyInput=false) at /tmp/buildd/insighttoolkit4-4.1.0/Modules/Filtering/FFT/include/itkFFTWCommon.h:242
242 plan = fftwf_plan_dft_r2c(rank,n,in,out,roflags);
ie whenever rank=2 and it is ok with rank=1
