[Boost-users] [multi-index] dereferencing the end iterator

Hello Joaquín,

today I faced some problem, when debugging the code.

namespace mi = boost::multi_index;

typedef mi::multi_index_container
    <
        vx_type
    ,    mi::indexed_by
        <
            mi::hashed_unique<mi::tag<vx_hash>, hash_extractor,
dummy_hasher>
        ,    mi::ordered_non_unique<mi::tag<vx_kind>, kind_extractor >
        >
    >                                                        some_t;

When created a view for vx_hash tag and going to change the invalid iterator
like view.end(). Dereferencing view.end() fails as awaited, but this code
which calls my TypeModifier:

view.modify(view.end(), my_modifier);

This will result in my_modifier call with dereferenced iterator, which
contains badly initialized object.

My environment VC++ 2005 Express,  boost 1.34.1

With Kind Regards,
Ovanes
