list::sort() doesn't work if value traits are stateful

[anonymous]

list::sort() uses temporary lists, constructed in this way:

list_impl carry; list_impl counter[64];

the list_impl constructor takes the value traits of the list as an optional argument, which must be passed in case the value traits are stateful.

I think it should be

list_impl carry(get_real_value_traits());
