Yes, that brush has two void areas. If you walk over, you'll get killed ("Barbie left a small crater"). The Wiki has some hints about ICHs, but I think it's not worth the work fixing that: the void areas are outside the playground and player should not go there anyway.^^

Just redo the brush, change it to solid before deleting it. Those collision hulls are semisolid, right ?
So change it to a solid ADD brush, build, then delete, build again, save map. then make new one. Not sure, but either have it touch no other brush, or have one edge touch a subtract brush.
If you already deleted it you must go back to the map before you deleted it.
Those collision problems can extend across a map and mess up some other completely unrelated area, or BSP hole, or instant death BSP. I always change semi solid to solid then rebuild, then delete, before I do more.
