--- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> ---
FWIW Clang says:

cv.cc:4:17: error: member function 'bar1' not viable: 'this' argument has type
'const Foo', but function is not marked const
                foo.bar1();
                ^~~
cv.cc:2:14: note: 'bar1' declared here
        void bar1() {}
             ^
1 error generated.


And EDG says:

"cv.cc", line 4: error: the object has type qualifiers that are not compatible
          with the member function
            object type is: const Foo
                  foo.bar1();
                  ^

1 error detected in the compilation of "cv.cc".
