Dear FLUKA Experts,
I hope this message finds you well.
I am currently running a FLUKA simulation where I aim to score information on protons crossing a specific boundary. To achieve this, I am using a user-defined mgdraw.f routine combined with a source.f routine.
Unfortunately, I am encountering errors that I am unable to resolve. Specifically, the simulation terminates with a segmentation fault:
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
Backtrace for this error:
#0 0x7f3a3527e5af in ???
#1 0x409a58 in master.0.mgdraw
at …/Routines/Mgdraw/AM_mgdraw_custom_2024v3.f:71

#7 0x7f3a3526a7e4 in ???
#8 0x40878d in ???
#9 0xffffffffffffffff in ???
and an error regarding the source executable:
I would greatly appreciate any advice or guidance on how to debug this issue further. I have attached for your reference my customized scoring routine, the routine used to define the source particles and the input files for the simulation setup.
Thank you very much for your time and support.
Best regards,
Antonella
