Take in care that intrusive containers don't store copies of objects but 
objects themselves. So in destroyMessage "hook" is going to be destroyed 
while inserted in m_message_list and that's why you get the assertion. 
See documentation:

http://www.boost.org/doc/libs/1_39_0/doc/html/intrusive/intrusive_vs_nontrusive.html#intrusive.intrusive_vs_nontrusive.differences_intrusive_vs_nontrusive

Maybe you just need std::list instead of intrusive.

Best,
