            Bug ID: 41192
           Summary: clang can't parse a global-namespace-qualfiied
                    qualified-id after a type definition
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Keywords: compile-fail
          Severity: enhancement
          Priority: P
         Component: C++

I believe this testcase is valid:

struct A;
struct B { static A a; };
struct A {} ::B::a;

Clang rejects this; it's apparently surprised to see a '::' appearing after a
class definition and incorrectly believes a semicolon was missing.

Interestingly, GCC rejects this too, in the same way. ICC and MSVC accept.
