TC <rs2740 at gmail dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rs2740 at gmail dot com --- Comment #1 from TC <rs2740 at gmail dot com> --- Since `*this` can't initialize an `A`, it's assuming brace elision. Not sure how the diagnostic can be made clearer though...perhaps it can report that assumption?
