MCWrapper GTRD segfault

[Patrick Moran]

Hello,

I am getting the segmentation fault below from MCWrapper. I am using the recon-2025_01-ver03 environment. Any idea what is going on?

My config file is located at /u/home/moranp/halld_my/MC_omega_bkg_x1.0.config

and the command I ran was $MCWRAPPER_CENTRAL/gluex_MC.py MC_omega_bkg_x1.0.config 132362 100

Looks like the version of the software you are trying to use is too old.  Try a more recent release.  I believe the latest version is version_7.8.0 .

That seemed to fix it. Thanks!
