             Bug #: 51927
           Summary: [C++0x] Cannot access non-static members in
                    initializer
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: gccearlyadopter@trash-mail.com


GCC47 doesn't allow to access non-static members in non-static member
initialization. The following program fails to compile with the error "invalid
use of non-static data member 'testee::l1'".

#include <iostream>
#include <functional>
using std::cout;
using std::endl;

struct testee
{
    std::function<void()> l1 = []()
    {   
        cout << "world" << endl;
    };  
    std::function<void()> l2 = [=]()
    {   
        cout << "hello " << endl;
        l1();
    };  
};

int main()
{
    testee t;
    t.l2();
}

Taking the address of l1 in the lambda expression used to initialize l2 is also
refused by GCC.
