When I test it as outlined in https://github.com/delphes/delphes

./DelphesSTDHEP cards/delphes_card_CMS.tcl delphes_output.root z_ee.hep

I get an error:

  • Reading z_ee.hep

What is wrong?

This cause of this problem starts with adding folder to gROOT->GetListOfBrowsables():

https://github.com/delphes/delphes/blob/master/modules/Delphes.cc#L72

then by deleting folder

https://github.com/delphes/delphes/blob/master/modules/Delphes.cc#L83

and then by Root exiting the executable and deleting the folder that is already deleted.
One needs to remove folder from gROOT->GetListOfBrowsables() together with deleting it.
