Core dump only on building hadron physics lists and not EM

Hello, I am having a G4 Exception - core dump on a specific cross section loading case (Hadr014), which is causing any application that used hadron physics lists to fail with the following error stream below. The build configuration and environment variables are also listed.

This is a new build and install for version 10.7p1, thus is not previously working code. No cross section data was transferred over from earlier use.

Condensed Error Output:

I have tested:

  1. The electromagnetic physics lists such as Em Opt0 EmOpt4 , and other example apps that do not use hadron physics lists and they work fine.

  2. Hadr01 - If I run Hadr01 without testing the physics lists, i.e. the example input file without /testhadr/ it works fine.

Also, I traced back the call for Hadr014 to geant4.10.07.p01/source/processes/hadronic/cross_sections/src where the code states:

There were no apparent failures in extraction of the relevent cross section data files for NDL, TENDL, and PARTICLEXS folders. I had also tried without the TENDL data as it’s stated these are optional online.

Thanks for any potential feedback

I have the same problem.
when I try to run the B2a example, after compiling it and doing $./exampleB2a, the visualization opens all right and when I click the Beam-On button, it produces the following output:

What shall we do?
[ I have installed and set up the environmental variables as in Postinstall Setup — Geant4 Installation Guide 10.7 documentation ]
Many thanks!

@iouatu sadly for me it was an environment variable issue, one of the cross sections paths was written wrong, double check which path variables doesn’t lead with G4

@marmolRBG , thanks for posting the solution!
For me it was the fact that I didn’t download and install al the datafiles from , but only the ones I ‘‘believed’’ will do the job.
For future reference, just download and install all datafiles from the start to avoid possible complications!
