Hello,

I ran a cvsup on current yesterday at around 9:50pm EST. Being curious if
the world compiles with -O2 yet, I gave it a shot. everything compiled
fine, no errors. After a mergemaster, and the reboot everything seemed
fine. At this point I went over to my windows machine (which uses the fbsd
box as a nat gateway) and I noticed that internet was not working. I was
unable to establish any TCP connections to the internet. DNS however was
working fine and TCP connections to the box itself worked as well.
Internet was also accessible from the fbsd box. I couldn’t find any
obvious errors in the configuration (it was not changed since the last
cvsup, ~3 weeks ago), so I decided to recompile without -O2, and
everything started working ok again. I understand that -O2 is not
officially supported, but maybe this can point out some problem that
should be looked in to. Here are my make.conf options that were used:

CPUTYPE?=athlon
CFLAGS= -O2 -pipe

Thanks.
