Have experienced the exact same bug, except with the latest SF4 (4.1.0). I have no crash log because of the hard freeze, and I'm running the game via the Twitch client with no extra mods loaded.

It's important to note that this only seems to happen after Minecraft has been running for a while (a few hours). It may also be related to the fact that the rifle I'm using (Phaser Rifle in my case) also has a scope like OP's.

The last exception before the JVM hard-locks is identical to the one posted by OP:
