------- Comment #2 from dragan at plusplus dot co dot yu 2009-07-08 12:38 ------- Although this is a feature request in the context that the old behavior was correctly implemented and it will be different in C++0x, it still presents a bug in the current C++0x implementation. It creates copies of objects that are returned by a rvalue reference, which would be wrong. I wasn't _really_ trying to request a new functionality, although I understand your concern.
However, IMHO in this particular case we are talking about one of the most fundamental features (binding a reference). This change could also expose possible bugs in the (user and library) code that relies on creation of a temporary, which even in C++03 is not considered a portable code. Don't tell me you'd rather deal with the issue after all the other C++0x stuff gets implemented... Anyway, my motive was to help the development of GCC. Personally, I didn't and will not rely on either of the two behaviors, but will try to write code that works in both situations. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40682
