            Bug ID: 26601
           Summary: Error for "return type 'V' is an abstract class"
                    missing for methods of a struct
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: -New Bugs

    Classification: Unclassified

The following program does not emit a diagnostic:

~~
struct V {
  virtual void foo() = 0;
};

struct S {
  V bar();
};

void test() { S().bar().foo(); }
~~

Presumably, it should emit an error that the return type of bar(), 'V', is an
abstract class.
