Geometry killed me while standing still in Intersection on Dire Marsh

On top of the isolated building in the southwest of Intersection, the one with the occasional green-laser traps, has a geometry that seems to have killed me while standing still. There are two large rectangular pieces of cover on the north-east corner that when I stood on them and stayed there for a few seconds, killed me. The kill feed said something along the lines of "critical system failure" as a the cause of death. 

I suspect there may be some out-of-bounds glitch here, where a killbox is located but not indicated? Or a killbox was once there and a residual bug has kept the place of that killbox.
