The underlying error is likely the same in both cases. An update in version 0.12.2 changed the error message that is displayed to be a bit more readable (“OpenMC aborted unexpectedly”). If you’re able to share your model, I can try to diagnose what exactly is happening and why you’re getting a segfault.
