optional_base::operator=() optimization

Reported by: rick68@… Owned by: Fernando Cacciola
Milestone: Boost 1.35.0 Component: optional
Version: Boost 1.34.1 Severity: Optimization
Keywords: Cc: fernando_cacciola@…

Description

Hi, 

A a1;
boost::optional<A> opt1(a1);
boost::optional<A> opt2;
opt2 = opt1;

the operator=() will call to assign(optional<U> const& rsh), not assign(optional_base const& rsh).
