Root crash for GetImageWithStatistic::SaveData TUnixSystem called from GATE/Geant4

_ROOT Version: Root 6.12/06
_Platform: Raspberry Pi running Raspbian (Debian) v9 (stretch)
_Compiler: Compiled from source with cmake

Hello all
I’m reasonably new to Root, and have been using it exclusively in conjunction with GATE/Geant4 as it is used to interact with the simulation. As a side project I have been trying to run GATE/Geant4 on a raspberry Pi. I am aware that this is not a supported platform for Root however hoped you may be able to help.

Root compiled successfully after expanding the allocated Swap during the installation process, I have since re-reduced it to the standard size. I can run Root and the included demos so I believe the installation is fine.

When I run a simulation, as it tries to use Root to write out the results I receive this error message:

*** Break *** segmentation violation

There was a crash.

I’ve tried to google the answer but my unfamiliarity means I’m not sure how to use the information that I can find for these error messages. If anyone could offer a pointer for me to try and fix this, that would be very much appreciated.
Thank you

There was a crash in GateImageWithStatistic::SaveData(int, bool). That’s not ROOT’s code - so we cannot help…

Thanks for the quick response - helps me rule out Root as the issue, I’ll take it to the GATE community.
Thank you
