Comment (by Kojiro Suzuki <pn.suzuki.kojiro@…>):

 Thank you for your answers, I understand it now.

 I have an idea.[[BR]]
 If you use the the previous code, and leave the assertion,[[BR]]
 it generates assertion without trying to allocate huge elements.

 {{{
     queue(void):
         head_(tagged_node_handle(0, 0)),
         tail_(tagged_node_handle(0, 0)),
         pool(node_allocator(), has_capacity ? capacity : 0) // add this
     {
         BOOST_ASSERT(has_capacity); // and leave this
         initialize();
     }
 }}}
