   What about this one:   
      
   int foo(int);   
      
   void bar(int foo = foo(12));   
      
   Here the name 'foo' in the expression 'foo(12)' would resolve to the   
   function parameter name 'foo'. After this has happened, we fall into   
   8.3.6 [dcl.fct.default] p9:   
      
   "[..] Consequently, parameters of a function shall not be used in a   
   default argument, even if they are not evaluated. [..]"
