Protip: Interlopers.net has a pretty neat tool to search your compile log for any errors, and it show you how to potentially fix them. I've linked it here. It's very handy in cases like this.

Anyways, the error is this: HashVec: point outside valid range

Either your map is way too big (which I doubt), or you have an invalid brush. Pressing ALT-P brings up a list of problems that could be in your map, which includes invalid brushes. Delete them and recreate them in a non-offending manner and you should be good to go.
