--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
clang gives:
<source>:7:8: error: member reference base type 'int' is not a structure or
union
T().waldo();
~~~^~~~~~
<source>:11:10: note: in instantiation of member function 'C<int>::f' requested
here
C<int> obj;
^
Which is definitely better.
