            Bug ID: 61987
           Summary: Name Resolution within a Template
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gaoyuanming at hotmail dot com

Created attachment 33222
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33222&action=edit
Assembly code

I compiled the piece of code:

#include <stdlib.h>

int foo(double d) { return static_cast<int>(d); }

template <typename T>
class Test
{
public:
        Test(int id, T const & value) : m_id(id), m_value(value) {}

        void change()
        {
                m_value = foo(m_id);
        }

        void change(int seed)
        {
                m_id = foo(m_value) * seed;
        }

        T value() const { return m_value; }
private:
        int m_id;
        T   m_value;
};

int foo(int n) { return n; }

int main()
{
    Test<int> t(10, 20);
    t.change();
    t.change(2);

    Test<unsigned long> tul(10, 30);
    tul.change();
    tul.change(3);

    return 0;
}

and found that the function void Test<int>::change(int) calls int foo(double)
to implement it. It is a bug.
