I try to keep my system updated daily, by "emerge sync"ing and then "emerge -Du world" on a daily or bi-daily basis. On 8-27-05 I sync'ed and then ran a -Du world, resulting in the updating of "sys-devel/gcc-3.4.4-r1". After several minuets my terminal was left the following test (please excuse any extra text, I'm fairly new to gentoo and this is my first bug. insn-attrtab.c: In function `insn_default_latency': insn-attrtab.c:7293: internal compiler error: Segmentation fault Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://bugs.gentoo.org/> for instructions. The bug is not reproducible, so it is likely a hardware or OS problem. make[2]: *** [insn-attrtab.o] Error 1 make[2]: Leaving directory `/var/tmp/portage/gcc-3.4.4-r1/work/build/gcc' make[1]: *** [stagefeedback_build] Error 2 make[1]: Leaving directory `/var/tmp/portage/gcc-3.4.4-r1/work/build/gcc' make: *** [profiledbootstrap] Error 2 !!!

I have verified that the ram is functional (13 passes of memtest come up clean) and the system is running completely at stock. At the time of the failed compile, I had KDE running, as well as Gaim, OpenOffice writer, two copies of Konqueror, Thunderbird, three copies of Firefox, SSH (was ssh'ed into a stage 2 gentoo compile), and two gnome-terminal windows open (one was the ssh into the other machine and one was the one in which was the "emerge -Du world"). I apologize if this bug report isn't formatted properly, I tried checking in IRC if anyone had any tips, but people just seemed mildly annoyed I was asking and ignored me.
By removing -msse3 from my cflags and adding sse3 to my use flags, I was able to compile gcc properly. Lesson learnt, Venice cores (that do support SSE3) do not like the -msse3 cflag.
