I get the crash: http://paste.ubuntu.com/8717431/
Happens after the chunk with the zombie loads.

I have no idea why this would happen, though it might be an issue with java, but that would be wierd if it was the case.

Yes, I started getting this today as well, in a world I've been playing in (with the latest version of Hunger Overhaul) for several weeks without a problem. Now that save is unplayable with the mod -- it crashes with the ticking entity message a few seconds after loading the save, and then refuses to load the save at all unless I remove the mod or switch to peaceful. Once I switch back to normal, the same crash happens a few seconds later.

Minecraft 1.7.10 and Forge 1232, BTW.

@zlepper, @Chadramar: Try this version and see if it's fixed: https://dvs1.progwml6.com/jenkins/job/HungerOverhaul-1.7.10/37/

Sorry for the late reply, but yes that appears to have fixed it for me. Cheers!
