Segmentation faults are usually bugs in the program where it is trying
to access memory it shouldn't be.  Very occasionally they can be
caused by hardware issues corrupting pointers, but usually it's just a
bug.

If, as Justin suggests, it's a problem in your simulation then I would
suggest that the program should detect it and tell you, not got off
into the weeds and trigger a condition that causes the OS kernel to
kill it with a SEGV.

Might be worth reporting a bug and seeing what the maintainers say.

cheers!
