Describe the bug

In ROOT 6.29 (dev3 LCG nightly slot on cvmfs) RooMomentMorphND cause segmentation fault.

(there is no fault e.g. for ROOT 6.26/04 ( LCG_102 LCG slot on cvmfs)

Expected behavior

No segmentation faults...

To Reproduce

My oversimplified script in https://gist.github.com/VanyaBelyaev/2373dae80b24b74d75026420efde8043

Usage on cvmsf, LCG dev3 nightly slot (ROOT 6.29/01) :

(  source /cvmfs/sft.cern.ch/lcg/views/dev3/latest/${CMTCONFIG}/setup.sh ; python ./tst_morph.py ) 

one gets segfaultt

while for LCG_102 slot on cevmfs (ROOT 6.26/04) everything is OK :

 (  source /cvmfs/sft.cern.ch/lcg/views/LCG_102/${CMTCONFIG}/setup.sh ; python ./tst_morph.py )
