"make buildworld" failure

Ahoy. I've been trying to build RELENG_8 from today a few times, and I'm 
beginning to suspect there's something wrong with my system. I've gotten 
several odd error messages, and have started writing them down. This 
last one is with a clean /usr/obj directory and a fresh checkout of the 
sources using csup.

Would bad RAM be responsible for something like this?
