I'm getting almost exactly what is described in MC-8849, which is marked as a duplicate of this bug.

I built a sky trap just below the build limit (roof is at y=255), and the game crashes occasionally with the "Adding entity to track" message. This has happened twice so far. Both times, the entity added was Squid. I'm using the current snapshot (13w10b).

Also, the entity count goes nuts at high altitude. Might be related...

Here's the error report. Email me if you need a copy of the world.
