I'd recommend asking this question in the EM Physics forum, as it sounds like you have been able to install Geant4 9.6 and then build your application against it(?). You could also try running the application with valgrind or through GDB to try and identify where the error occurs.

Please also post as much information as possible - we need to know what OS your are building/running on, the compiler family and version used to build, and what arguments and options you passed to CMake when building. It's impossible for use to provide reasonable help and advice without this information.
