--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> ---
This is essentially fixed:

42021.C: In member function ‘void BreadSlicer::print()’:
42021.C:26:19: error: reference to ‘P3’ is ambiguous
         Policies::P3::doPrint();
                   ^
42021.C:10:21: note: candidates are: typedef struct Policy1 B::P3
     typedef Policy1 P3;
                     ^
42021.C:14:21: note:                 typedef struct Policy2 C1::P3
     typedef Policy2 P3;  
                     ^

Nit: we emit the diagnostic twice. I have a patchlet for that:
