[Boost-users] [ptr_container] view_clone_allocator with associative containers

1 Mar 2010


      I cannot get the view_clone_allocator to work with associative containers, as
in the example below:

    boost::ptr_vector<int> vec;
    boost::ptr__map<std::string, int, boost::view_clone_allocator> map;

    int* i = new int(42);
    vec.push_back(i);

    std::string k("foo");
    map.insert(k, i);
...
From the error message, it seems that the CloneAllocator is still of
type boost::heap_clone_allocator.
Why is this failing? It seems intuitive to specify the allocator as
third parameter, similar to the example with ptr_vector where the 
allocator is the second argument.
