cmssw: ROOT 6 master: Histogram merge error

IN the ROOT6 IB, we are periodically seeing workflows (e.g. 137.8) failing in the DQM Harvest step from a new ROOT error message

adding @yamaguchi1024 as we talked of similar issues a week ago in the context of root modules…

@pcanal @smuzaffar This seems extremely bad. This is implying that ROOT6 master can only run on a machine on which it was compiled. We need to determine what differences between the docker container and lxplus7 are causing the problem and make ROOT not care about them (since such diffferences are bound to happen on grid sites as well).
