---------------------------------------------+------------------------------
 `base_from_member` constructors take their arguments by value, which
 causes undefined behavior if the member type is a reference, as a dangling
 reference is created (unless, I presume, its initialized with
 `boost::ref/cref`).

 The attached patch adds a partial specialization of `base_from_member` for
 references. It provides a single constructor that takes its argument by
 reference.
