FreeBSD make buildworld fail: cc: Internal error: Killed: 9 (program cc1)

[Traiano Welcome]

Hi All

 I'm trying to upgrade from FreeBSD 8.0-RELEASE #0 to FreeBSD 8.2 or
better. My upgrade sequence would be as follows:

 0. cd /usr/src/;make cleanworld (and in extreme cases rm -rf /usr/src/*
and rm -rf /usr/obj)
 1. csup -L 2 stable supfile.
 2. cd /usr/src; make buildworld && make buildkernel && make installkernel
&& make installworld && reboot
 3. mergemaster -p && make installworld && mergemaster && reboot


My stable-supfile is as follows:

---
 *default host=cvsup2.za.freebsd.org
 *default base=/var/db
 *default prefix=/usr
 *default release=cvs tag=RELENG_8_2
 *default delete use-rel-suffix
 src-all
---


 However, I'm not getting past "make buildworld". Below is the tail end of
my make buildworld:

My questions are:

- Is this a known issue (can't  seem to find much on google) ?
- If not, how would I go about pinpointing the root cause of this compile
error. Upping the make debug level doesn't seem to get my any more
detailed information that I can use .

I've run csup multiple times (with multiple make clean;make
cleanworld;make cleandir in between) across 48 hours , but each update  to
my source tree doesn't seem to get any different result.

I've also tried upgrading my userland tools before doing the upgrade
(portupgrade -a) in the hope that the my compiler tools might have been
updated to fix this.


Any advice would be appreciated,
Traiano
