I compiled the actual snapshot 20041205 with gcc from last week using
../gcc40/configure --prefix=/usr/local/gcc40c --program-suffix=40c --with-
arch=opteron --enable-languages=c,c++ --enable-checking
and
CFLAGS="-pipe -g -O3 -march=opteron -fmessage-length=0 -falign-loops=16
-falign-jumps=16 -falign-functions=32 -fstrict-aliasing -fsched-interblock
-ffast-math -funroll-all-loops -funit-at-a-time -fpeel-loops -ftracer
-funswitch-loops -loop-optimize2 -fmove-loop-invariants -fgcse-after-reload
-frename-registers -modulo-sched --param max-gcse-passes=5
--param max-unrolled-insns=600 --param inline-unit-growth=300
--param large-function-growth=400"
I got an segfault on my opteron system and an ICE on a ppc system.
On both system I did a full boostrap using
CFLAGS="-pipe -g -O2 -march=opteron -fmessage-length=0"
CFLAGS_FOR_BUILD=<full options>
On both system this bootstrap completed.
I installed the compiler, cleared the object dir and did a configure / make
with CFLAGS=<full options>.
On both systems I got ICEs as shown below.

This works on the 3.4 branch so it is a regression from there.

I needed to add -floop-optimize2 to make the reduced testcase fail on power-linux.
