--- Comment #4 from Denis Sherstennikov <ddsherstennikov at ya dot ru> --- Yes, it does. That clearly ain't an obvious fix. If you hadn't told me, I don't know how I would figure this out in short time. I'd appreciate a compiler warning on this issue with direct designation of the choices and corresponding g++ flags. Also, is there a record on this change-of-behavior in g++ 5.2/5.3 changelog? I did not see any.
