I am currently working with a MC calculator for position resolution in silicon detectors.
The code is available here (github.com/simonspa/resolution-simulator) and it is ran on lxplus. It requires ROOT and an external library (GBL) from here (gitlab.desy.de/claus.kleinwort/general-broken-lines).
The framework compiles without any errors on lxplus. However, I am unable to run any example file (from the build/devices directory). Any command just hangs…
To initialize the environment, a shell script is available (init_x86_64.sh) in the first mentioned repository. This prepares LCG_101 from cvmfs/sft.cern.ch/x86_64-centos7-gcc11-opt//lcg/views/ with GCC as compiler, version gcc11.
The version of ROOT is 6.24/06
To see what happens behind I am using gdb. Here is the output:
(gdb) add-auto-load-safe-path /cvmfs/sft.cern.ch/lcg/releases/gcc/11.1.0-e80bf/x86_64-centos7/lib64/libstdc++.so.6.0.29-gdb.py

I am unfortunately unable to understand what is wrong from here. I was hoping for some tips going through this stack trace and figuring out why ROOT seems to be stuck printing a warning…
Note: Beginner here, please bare with me
