Actually I have several Alpha's, and one I have to reload due to this, so I will give this a try on the other machine and will let you know if I have good success with it. If this all works, then I agree with you that we want to avoid, or at least note the problem with -O2 as I have been using that when making software on my Intel machines for a long time, so just assumed it was OK to do the same on the Alpha.. > Get rid of -O2 in /etc/make.conf; comment out the CFLAGS line.
