--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- It's not very clear to me what an aligned attribute on a reference, or a check of the alignment of a reference, should mean anyway. Note that in some places, [[]]-style attributes appertain to different syntactic constructs than __attribute__ appertains in the same place (and in any case, what [[]] appertains to is more precisely defined, whereas what __attribute__ appertains to is what keeps compatibility with existing code). C++ alignas can be applied to references, but I don't see anything in [dcl.align] to clarify what it means there - does it align the referenced type (so that it's only valid to bind the reference to an object that itself is sufficiently aligned), or something else?
