           Summary: getLinkageAndVisibility(): Assertion `LV ==
                    computeLVForDecl(this, false)' failed
           Product: clang

Hi,

the following code causes an assert in a clang Release+Asserts build of trunk.
Similiar issues were fixed in Bug#14835 and bug#14898 but this example still
fails. I am setting it to release blocker since it worked previously and also
in an earlier post-3.2 version of trunk.


class TemplateArg1
{
};

class TemplateArg2
{
};

template <typename T1>
class Class1
{
  void f1()
  {
    f2();
  }

  inline void f2()
  {
  }
};


template<>
inline void Class1<TemplateArg1>::f2()
{
}

template<>
inline void Class1<TemplateArg2>::f2()
{
}

template class __attribute__ ((visibility("default"))) Class1<TemplateArg1>;
