Hello Joaquín,<br><br>today I faced some problem, when debugging the code.<br><br>namespace mi = boost::multi_index;<br><br>typedef mi::multi_index_container<br>&nbsp;&nbsp;&nbsp; &lt;<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; vx_type<br>&nbsp;&nbsp;&nbsp; ,&nbsp;&nbsp;&nbsp; mi::indexed_by<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &lt;
<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; mi::hashed_unique&lt;mi::tag&lt;vx_hash&gt;, hash_extractor, dummy_hasher&gt;<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; ,&nbsp;&nbsp;&nbsp; mi::ordered_non_unique&lt;mi::tag&lt;vx_kind&gt;, kind_extractor &gt;<br>&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &gt;<br>&nbsp;&nbsp;&nbsp; &gt;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; some_t;
<br><br><br>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:<br><br>view.modify(view.end(), my_modifier);
<br><br>This will result in my_modifier call with dereferenced iterator, which contains badly initialized object.<br><br>My environment VC++ 2005 Express,&nbsp; boost 1.34.1<br><br><br>With Kind Regards,<br>Ovanes<br><br><br><br>
