*** Break *** segmentation violation Generating stack trace...

Asked by yvonne ng

Hi,

So I imported a model,
Added a process and output successfully, but when I try to launch it gives me this error.
online searching tells me that this error is related to C++ and that somethings are not correctly referenced?
I wonder if anyone has ran into this problem before and can tell me what this is caused by.

*** Break *** segmentation violation Generating stack trace... 0x0000000105f49788 in ExRootTreeWriter::NewBranch(char const*, TClass*) (in ExRootLHEFConverter) + 40 0x0000000105f4f15f in main (in ExRootLHEFConverter) + 575 0x00007fff8bb695fd in

Hi,

madgraph do not use any C++, so the problem is either in Delphes or in the ExRootAnalysis package (both external package).
Pavel is one author of both package and might be able to help you.

Cheers,

Olivier

Hi it was indeed an Exrootanalysis problem. i reinstalled root after the initial installation and I think that was what that lead to the problem.
Thank you so much for your help!
