Unless there is a bug (something that is of course, possible) if the assertion reaises in this function of avltree.hpp:
iterator insert_unique_commit (node_algorithms::unique(to_insert)); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
means that you've using a safe hook (the default one) and before inserting an object, the container checks that the hook is in default position (unique() is true). If it's not that means that the hook is still use (the value is still inserted in another container). The testsuite includes avl containers with offset_ptr<> pointers but this might indicate a bug in Intrusive. Please check if that object is still in another container and if not, it would be nice if you could provide a test case that raises the bug.

Hi Ion, find a simplified test case attached that reproduces my findings. Hopefully this will allow you to find the problem wether it is in my code or the library. g++ -o avltest -I/opt2/linux/x86_64/include/boost-1_35 -DUSE_OFFSET_PTR=1 avltest.cpp avltest.cpp:23:2: warning: #warning with offet_ptr rm /tmp/avltest.img; ./avltest sizeof(BalanceNode)=32 sizeof(BalanceSet)=32 creating file ... creating file done header.get_address()=0x7fb86cc72000 header.get_size()=128 region.get_address()=0x7fb86cc71080 region.get_size()=224 p_set=0x7fb86cc71080 p_values (before)=0x7fb86cc71080 offset=64 initializing header ... initializing header done p_header->m_avail=5 p_header->m_count=0 initializing set ... initializing set done p_values (after) =0x7fb86cc710c0 creating entry 0 ... creating entry 0 done int=84 inserting entry 0 ... avltest: /opt2/linux/x86_64/include/boost-1_35/boost/intrusive/avltree.hpp:618: boost::intrusive::tree_iterator<boost::intrusive::avltree_impl<Config>, false> boost::intrusive::avltree_impl<Config>::insert_unique_commit(typename std::iterator_traits<typename boost::intrusive::detail::eval_if_c<boost::intrusive::avltree_impl<Config>::external_value_traits, boost::intrusive::detail::eval_value_traits<typename Config::value_traits>, boost::intrusive::detail::identity<typename Config::value_traits> true>, safe_link, boost::intrusive::default_tag, 6>, std::less<BalanceNode>, long unsigned int, true>]: Assertion `node_algorithms::unique(to_insert)' failed.
