All kinds of weird problems started popping up, with the most annoying of them all an invalid checksup on all UDP and TCP packets my machine tried to send over dialup interfaces like ppp0 or tun0. Switching to a plain `-O -pipe' setting in make.conf made all of the problems go magically away. That was the last time I used optimizations in buildworld and buildkernel, as far as I remember :) Strange because in the Linux camp they are all madly optimizing, but since I hate unpredictability compared to a loss of speed, the choise is obvious for me thereafter.
