Thanks for posting. At this stage it’s hard to say whether ROOT is responsible for this crash, however, your report can be useful for an internal ALICE forum where software issues are discussed: could you try to get feedback there? If then it turns out it’s a behaviour related to ROOT, don’t hesitate to post.
