Using FunctorImageFilter with a neighborhood of vectors

Description

I am trying to use the new functorImageFilter (!299 (merged)) with a lambda taking an itk::Neighborhood<itk::VariableLengthVector<float> > as input, but I get a segfault when I try to use the filter.

Below is the pipeline I use :

  auto reader = ReaderType::New();
  reader->SetFileName(filenameIn);
  
  // Dummy lambda that takes a neighborhood of vectors as input and return 1
  auto lambda = [](const itk::Neighborhood<itk::VariableLengthVector<float> > & in)
  {
    float out(1);
    return out;
  };

  auto filterLambda = otb::NewFunctorFilter(lambda ,{{3,3}});
  filterLambda->SetVariadicInputs(reader->GetOutput());

  auto writer = WriterType::New();

  writer->SetInput(filterLambda->GetOutput());
  writer->SetFileName(filenameOut);
  writer->Update(); //segfault

The code compiles but throw a segfault (in the threadedGenerateData() of functorImageFilter, when calling the CallOperator() method)

Note that this pipeline works correctly if the lambda takes a itk::Neighborhood<float> instead of the itk::Neighborhood<itk::VariableLengthVector<float> >

Am I missing something in the configuration of the lambda or the functorFilter ? Do we have any example of functorFilter using neighborhood in the OTB at the moment ?
