Jiang An <de34 at live dot cn> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |de34 at live dot cn --- Comment #10 from Jiang An <de34 at live dot cn> --- I think this is basically CWG2709 (https://cplusplus.github.io/CWG/issues/2709.html). Given CWG2709 is closed as NAD, we should reject such initializations.
