I'm running 64 bit 1.3.1 with several mods (Airplane Plus, Autogarage, BD Armory, Chatterer, KAS, Near Future Solar, plus a few others), and the game crashes right after it finishes loading. The problem surfaced when I installed Kerbal Konstructs, but removing it stopped the crashes.
I'm not running out of memory, and since it's 64 bit KSP, it *should* run fine.
Here's a crash log:

EDIT: Removing Kerbal Konstructs didn't decrease memory usage much. The game would crash at ~2.1GB, but it's running fine (without Kerbal Konstructs) using 2.6GB.
