when I was upgrading to 4.5 RC1 and I tryed to do make world first in /usr/src and it broke after a several minutes of running so what I did was a make clean and tryed it again and it did the same. I've included the a last bit of the make world where it died.
Although when I did a make buildworld everything went ok. Then I compiled the kernel and rebooted and its been running ever since. Bri,
makeworld.log
