Hi,

current mainline (revision 122038) produces an ICE in stage 2 when configured
with --with-arch=athlon64:

~/rcs-data/gcc-svn/configure --prefix=$HOME/env/gcc --enable-languages=c
--with-arch=athlon64 && make

...

When configured without --with-arch=athlon64 the build succeeds. The problem
has probably been introduced since 2007-02-09.
