Hi rooters, I am observing strange feature. The TMultiDimFit object works fine except if created with an option "k". Without this I am getting the coefficients until the warning "TMultiDimFit::MakeCoefficientErrors>: curvature matrix is singular" which seems to be handled. With an "k" option this seems lead to crash. I tested it with an vendor-root example. Just add use "vk" while creating the fitter and you will have the feature reproduced.
