            Bug ID: 57818
           Summary: A strange template output
           Product: gcc
           Version: 4.8.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: liweifriends at gmail dot com

Hi: I have tried the following code in gcc 4.8.1

template<const float* b>
struct h
{
    static constexpr float value()
    {
        return *b;
    }
};

constexpr float a = 3.0f;

int main()
{
    cout<<a<<endl;                //3
    cout<<h<&a>::value<<endl;     //1
    return 0;
}

the output of h<&a>::value seems not correct. Is this a bug? Or just because
the unsupported of C++ ?

It seems incorrect because you have:

  h<&a>::value

instead of:

  h<&a>::value()
