https://issues.dlang.org/show_bug.cgi?id=22499 Issue ID: 22499 Summary: Copy construction of nested struct rejected Product: D Version: D2 Hardware: All OS: All Status: NEW Keywords: rejects-valid Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: timon.gehr gmx.ch DMD 2.098.0: --- auto makeFoo(){ struct Foo{ this(ref typeof(this)){} } return Foo(); } void main(){ auto foo=makeFoo(); auto bar=foo; // error } --- Yields: --- Error: cannot access frame pointer of `tt.makeFoo.Foo` --- This makes no sense, as there is a frame pointer in foo that can just be copied over to bar before calling the copy constructor. core.lifetime.copyEmplace actually handles this case correctly. --
