Hello RegCM’ers, I’m trying to create a domain centered on the Gulf of Alaska using a Lambert Conformal Conic projection (LAMCON) and terrain is segmentation faulting. I’ve played with the domain extent and center and the crash seems to happen once you span the date line. I’m using RegCM-4.7.1. I’ve created the standard 50 km NARRCAP domain in the past that can cross the boundary a little, but I am having no luck with this model version and domain.

Does anyone have suggestions for an Alaska / Beringia domain? 

Here is the failure output:
