hmmm....seems there is a problem with gcc. this is what i get during
buildworld:

i've ran buildworld twice (with a clean /usr/src and non-existing /usr/obj/*)
and got the error twice, so it's not a hardware problem it seems.

if i'm not mistaken the gcc that is being used for buildworld is not the one in
/usr/bin, but a fresh build in /usr/obj, right?

this is the bt from "gdb /usr/obj/usr/src/tmp/usr/bin/gcc gcc.core". i hope i
picked the correct gcc executable:

Core was generated by `gcc'.
