      Description

      Hi. When using the DataFrames I noticed that I get a segmentation violation when defining a new column that has the same name as an existing variable.

      e.g.:
      d = ROOT.Experimental.TDataFrame("foldername", "filename.root")
      d.Define("weight", "var_1+var_2")

      crashes, when there is already a variable called "weight" in the input tree.
      I would suggest to check this within ROOT first.

      Cheers,
      Raphael
