gcc 4.3.4 (SLE 11) produced wrong code. It seems that the compiler does not create a copy of an object "s" and returns an object of D().

Hmmmm - this is what I would expect it to do.

Yes, but this function from boost::container::flat_map library ( https://github.com/boostorg/container/blob/develop/include/boost/container/f... ). Not in my code.
