I found the second bug and I think it's related to the first report. 
 
/ -O0 on all tests / 
 
With -march={i[3456]86,athlon} gcc works fine. 
With -march=pentium[34] gcc fails: 
 
In file included from /usr/include/gtk-2.0/gtk/gtk.h:156, 
                 from gtkpeer.h:39, 
                 from gthread-jni.h:43, 
                 from gnu_java_awt_peer_gtk_GThreadNativeMethodRunner.c:40: 
/usr/include/gtk-2.0/gtk/gtktoolbar.h:144: internal compiler error:

Now I'm sure. It's kernel related bug. 
 
With 2.6.9rc2+20041007_0305 everything works fine. 
After update to 2.6.9rc4 lots of things stop working.
