CMSSW build fails with root master 4c13caa0ac

[smuzaffar]

we are testing latest root changes in cmssw and we are getting error [a] in ROOT::Fit::Fitter code. Could it be related to change in this PR? Note that root master commit f1e8d0c works fine.

By the way, the CMSSW code which calls Fitter::FitFCN is https://github.com/cms-sw/cmssw/blob/6d2f66057131baacc2fcbdd203588c41c885b42c/RecoPPS/ProtonReconstruction/src/ProtonReconstructionAlgorithm.cc#L269-L281
