i was trying to upgrade GCC on my gentoo box:
---------- CODE ----------
localhost linux # emerge gcc -pvt
These are the packages that I would merge, in reverse order:

CFLAGS=CXXFLAGS="-march=k8 -mtune=k8 -Os -s -pipe -fomit-frame-pointer"
i've tried every -O levels, removing -s, removing -pipe, removing -fomit-frame-
pointer, still the same error
hardware is OK. over 30 passes of the newest memtest86+ without errors.
partitions (ext3) checked for inconsistency twice. CPU/RAM underclocked by 30%
to be sure (overclocked to 155% of nominal power gives the same error).
moreover this SegFault can sometimes screw the whole system - almost every user
action results in segfault after that error.
