What is the principle for behavior of boost adding month?

I hope this helps you . This behavior is mentioned in the documentation of boost::date_time::month_functor.

How can I have a behavior-rich domain entity that adheres to Open-Closed Principle?

around this issue It's useful to keep the open-closed principle (OCP) in mind when designing classes, but it's not always practical or desirable to make classes "closed for modification" right away. I think the single responsibility principle (SRP) is much more useful in practice -- as long as a class only does one thing, it is okay to modify it if the requirements for that one thing change.
Moreover, SRP leads to OCP over time; if you find yourself changing a class often, you would eventually refactor it so that the changing portion is isolated in a separate class, thus making the original class more closed.

Do we apply DRY principle only to the state of the object or also to its behavior?

I hope this helps you . 1) "information" refers to any piece of code:
from a large code snippet (manually calculating the square root of a number all over the place should be replaced with a Sqrt method) to a simple value (using the string "Monday" all over the place, should be replaced with an enumeration of the days in a week).

boost::atomic with boost::optional different behavior with boost 1.55 and 1.58

I think the issue was by ths following , Like std::atomic, boost::atomic requires trivially copyable types. boost::optional is not trivially copyable, so you just get undefined behavior.
By the way, compare_exchange_* compares the objects as if by memcmp, so it would take into account any padding bytes as well.

Strange behavior change in boost::bind / boost::function since 1.55

wish helps you The problem is that boost::function has become stricter in matching the function signature (I think to more closely match the behavior of std::function). Your function is declared to be boost::function3< void, Arg1, Arg2, Arg3 >, however, the function you're binding to it takes int const& and int&.
There are a couple of ways to fix this. You could:

boost::any violates Liskov substitution principle

this will help I don't think it "violates" it - boost::any isn't designed for what you're using it.
It is specifically designed to work with value types (see the docs, to which you already posted a link).
