This clearly points at a compiler bug, with the VIA cpu, but since 
world/kernel build cleanly and anything else bugs out quite early, I would 
suspect an optimization bug.
Could you set the following in /etc/make.conf:
CFLAGS=-pipe -O0 # capital O, number zero

As a shortcut, you could go to the ruby workdir:
cd `make -f /usr/ports/lang/ruby18/Makefile -V WRKSRC`

then type:
cc -pipe -O0 -fPIC -DRUBY_EXPORT -I. -c array.c

Then again, it could be the compiler you built yourself is broken. Easy to 
test if you can rebuild world again now.
