9650	intrusive list with stateful value traits	Matei David <matei@…>	Ion Gaztañaga	"In 1.55, in file `boost/intrusive/list.hpp`, in function `list_impl::iterator_to()`: when `list_impl` is instantiated with stateful value traits, the function attempts to call a non-static member without an object.

The problem is that `list_impl` does not derive from `value_traits`, instead, only its member `data_` derives from `value_traits`. Then, inside the non-static `iterator_to()`, the syntax `real_value_traits::to_node_ptr()` is incorrect. In contrast, e.g., `bstbase3` does derive from `value_traits`, and there the same syntax works just fine.

I'm attaching a file demonstrating the bug. The file contains the sample code at the bottom of
http://www.boost.org/doc/libs/1_55_0/doc/html/intrusive/value_traits.html
with a single line modification invoking `iterator_to()`. I'll create a pull request."	Bugs	closed	To Be Determined	intrusive	Boost 1.55.0	Problem	fixed	intrusive list iterator_to with stateful traits
