Hi,
I have a segfault on lxplus7 when loading a TEve example, with the software configured from the LCG stack. To reproduce:
source /cvmfs/sft.cern.ch/lcg/views/LCG_95/x86_64-centos7-gcc7-opt/setup.sh
|
root ${ROOTSYS}/tutorials/eve/geom_lhcb.C
|
And I get a segmentation violation in:

I get the same problem with the LHCb install of LCG 95.
Could you have a look ?
Many thanks !
