*sigh* 3.3.1.29638 crashes too, I'll restate specs again: W7 x64, 16GB RAM, i5-3570k, Avast 8.0.1489 antivirus (crashes happened with v7 and other v8's), Comodo Firewall 5.10. 3.2.3.28705 is the last version that doesn't crash for me, seems anything in the 3.3 and 3.3.1 branch crashes. 3.2.3 I can leave running for days, 3.3 and 3.3.1 crash after an hour or two. I tried your settings a few versions ago, crash. Haven't run as admin, but I don't see how admin will fix it. ATM I'm not going to do admin and 3.3 or 3.3.1 b/c I'm going to leave this unattended so I'll be running 3.2.3. Let me know if you need any other specs/software.
