Segmentation fault

Many apologies if this is in the wrong category,
Hi, when using my group’s geant4 monte carlo I am experiencing a segmentation fault of which we are unable to debug. If any one can identify the root of this fault it would be greatly appreciated.

Here is the stack trace, my OS, compiler and geant4 version,
Ubutunu 18.04
Geant4-10.6.2
gcc 7.5.0

There was a crash.
