Error in <TObjArray::At>: index -32649 out of bounds

[Sergei Chekanov]

Hello,

I have very busy events with 140 pile up events at 14 TeV (using HEPMC). Delphes3 breaks on such events with the attached error.

I should say it works fine when I have 50 and 100 overplayed pileup events, it start to give problems when the number of overplayed events more than 140.

best, Sergei
