             Bug #: 55409
           Summary: std::list not properly wrapping access to custom
                    allocator through allocator_traits
    Classification: Unclassified
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: libstdc++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: benjamin.kircher@gmail.com

Small example showing simple custom allocator with std::list and std::vector

The attached source file compiles fine with a std::vector as container_type.
Using std::list however, compilation fails with the error message given below.
Expected behavior is that it compiles with std::list as like with std::vector.

$ gcc --version
gcc (Debian 4.7.2-4) 4.7.2


$ cat main.cpp
template<typename T> class my_alloc
{
    // class template supporting the minimal interface according to 17.6.3.5
};

int main()
{
    //typedef std::vector<int, my_alloc<int>> container_type;
    typedef std::list<int, my_alloc<int>> container_type;
    container_type cont;
    cont.push_back(11);
    cont.push_back(22);
    cont.push_back(33);
    return 0;
}


$ g++ -g -std=c++11 -Wall -Wextra -pedantic main.cpp
<snip>
/usr/include/c++/4.7/bits/stl_list.h: In instantiation of ‘class std::list<int,
my_alloc<int> >’:

and so on.
