Hi Lorenzo, Issue 1 is a bug in the implementation of Optional that I introduced a couple of days ago. This has been now reverted, but we will still see the error reports for the next couple of days in the test matrix. Issue 2 seems to be the communication problem between the compiler and the standard library, but I do not know anything specific.
FWIW I'm getting an error on the develop branch using g++ 4.4 in C++0x mode: ../../boost/optional/optional.hpp:954: error: ‘boost::optional<T>::optional(boost::optional<T>&&)’ cannot be defaulted ../../boost/optional/optional.hpp:1031: error: ‘boost::optional<T>& boost::optional<T>::operator=(boost::optional<T>&&)’ cannot be defaulted g++ 4.6 doesn't have this issue.
