Hadd command segmentation

ROOT
1

Dear expert,

When I try to use hadd command to merge some DAOD files, I got an error “ *** Break *** segmentation violation”

  1. asetup 23.6.51,AthGeneration to create EVENT.root

  2. asetup Athena,main,latest to create DAOD.root TRUTH3

    Now the latest verison is Athena/25.0.44

  3. Under the environment Athena,main,latest, I can open the root file successfully.
    Then when I want to merge several DAOD files, hadd got an error *** Break *** segmentation violation

My files are smaller enough~ 100MB
I can attach two files link:

  1. CERNBox

Could you please give me some advice?
Many thanks in advance!

What ROOT version are you using?

Did you try with the latest one and still see the crash?

I cannot access the ROOT files you linked (they are protected)

Could you also copy-paste the full error message?

Hi,
these are obviously ATLAS-specific files in an ATLAS-specific environment. Generally it’s not a good idea to merge them with hadd. Why do you need to do that at all? If this is really necessary, try doing so with the AODMerge_tf.py transform (for more details, see AODMerge_tf.py --help).
