The code had a typo it was doing:
Param->setUninstantiatedDefaultArg(Param->getUninstantiatedDefaultArg());
This is a no-op but may assert, we wanted to do:
Param->setUninstantiatedDefaultArg(OldParam->getUninstantiatedDefaultArg());
This fixes PR28082.

Example:
template <class T>
class A {
public:
template <class U> void f(U p) { }
template <> void f(int p) { } // <== class scope specialization
};
This extension is necessary to parse MSVC standard C++ headers, MFC and ATL code.
BTW, with this feature in, clang can parse (-fsyntax-only) all the MSVC 2010 standard header files without any error.
