[boost] [optional] can I merge a performance bug fix?

Hi, Could I still merge this pull request for Boost.Optional for 1.56 release. https://github.com/boostorg/optional/pull/6 It fixes a negative performance impact added since 1.55 in cases like: consumeOptional(*produceOptional()); This code already used to seat in develop before I added a bug) and all tests passed fine. Now, the fix has been there since friday on develop and I have no test failures. Can I merge it to trunk? Regards, &rzej
