--- Comment #30 from Rich Felker <bugdal at aerifal dot cx> --- I don't really understand how weak aliases come into play for implementing C++ features, but if their semantics are not identical to the necessary C++ semantics, the compiler should just distinguish between the relevant C++ semantics and weak alias semantics rather than trying to force two semantically different concepts to use the same feature in ways that breaks either one or the other. Also, was C++ behavior broken prior to 4.9.0, or is there some other reason that weak aliases worked without breaking C++ mandatory constant folding prior to 4.9.0?
