           Summary: clang uses the regparm attribute when deciding
                    templace specializations
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

Clang rejects and gcc accepts the following code:

template <typename Method> struct nsRunnableMethodTraits {
};
//template <class C> struct nsRunnableMethodTraits<void __attribute__ ((regparm
(0))) (C::*)()> {
template <class C> struct nsRunnableMethodTraits<void (C::*)()> {
typedef int base_type;
};
template<typename Method> typename nsRunnableMethodTraits<Method>::base_type*
NS_NewRunnableMethod(Method method) ;

struct C1  {
  virtual void __attribute__ ((regparm (0))) FinishStream(void) {
    NS_NewRunnableMethod(      &C1::FinishStream);
  }
};

Changing which line make clang accept the code.
