Description David Kilzer 2013-11-22 08:27:56 PST 
Reduced test case:

typedef struct mystruct { } *mystruct_t;
class MyClass {
 static const MyClass* create(mystruct_t q);
};
const MyClass* MyClass::create(mystruct_t q) { return 0; }
extern "C" {
 const MyClass* _ZN7MyClass6createEP8mystruct(mystruct_t q) { return 0; }
}

Original arguments used to reproduce (on Mac OS X 10.9) with trunk clang r194422:
