           Summary: Lambda expressions: access to member functions
           Product: gcc
           Version: 4.5.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassig...@gcc.gnu.org

According to the latest C++0x draft (n3126), 'this' is not required in front of
the member variable 'f' (there are a few examples on this issue in the draft).
As far as I understand, the same should apply to a member function. In GCC
4.5.0, the use of inc(n) without   the prefix "this->" causes an error.

struct S10 
{
    int f;
    double p;
        void inc(int& a) { a += f;}
    void work(int n) 
    {
        int m = n*n;
        int j = 40;
        f = 10;
        p =3.7;
        auto m3 = [this,&n]() mutable -> int
        {
            p++;
            f++;       
                        inc(n); //this-> required in 4.5.0               
            return n;
        };
        cout << "S9 m3():" << m3() << endl;
        cout << "f:" << f << " p:" << p << " n:" << n << endl;
    }
};
