--- Comment #3 from Jonathan Wakely <redi at gcc dot gnu.org> --- I'm inclined to say this is a Clang bug too. [stmt.return]/3 "A return statement with an expression of type void can be used only in functions with a return type of cv void;" and constructors do not have any return type, not even void. [class.ctor]/8 "A return statement in the body of a constructor shall not specify a return value." That doesn't really help, because a return statement with an expression of type void does not return a value.
