http://d.puremagic.com/issues/show_bug.cgi?id=515 Summary: Spec incorrect in where .offsetof can be applied Product: D Version: 0.174 Platform: PC URL: http://www.digitalmars.com/d/class.html OS/Version: Windows Status: NEW Keywords: spec Severity: normal Priority: P4 Component: DMD AssignedTo: bugzilla@digitalmars.com ReportedBy: deewiant@gmail.com OtherBugsDependingO 511 nThis: The spec has code amounting to the following, under "Field Properties": class Foo { int x; } void main() { Foo foo = new Foo(); size_t o; o = Foo.x.offsetof; o = foo.x.offsetof; } The spec states that the above of the two assignments to o should yield 8 and the below should fail to compile. DMD's behaviour is precisely the opposite. The explanation confused me somewhere around "fields qualified with the type of the class" so I'm not sure which is right, but one of the two - the spec, or DMD - has to be wrong. -- |

I'm therefore inclined that DMD is wrong. -- |

Posted in reply to d-bugmail | http://d.puremagic.com/issues/show_bug.cgi?id=515 ------- Comment #4 from wbaxter@gmail.com 2008-07-02 03:52 ------- Just a ping that the spec (http://www.digitalmars.com/d/1.0/class.html) is still not in line with the compiler (DMD 1.031). You can see it first mentioned regarding DMD 0.131 back in 2005 here: http://www.digitalmars.com/d/archives/digitalmars/D/bugs/4988.html Just to recap: In the compiler Foo.init.x.offsetof works. Foo.x.offsetof does not. Spec says the opposite is true. -- |

This basic issue of this bug has been fixed by changing the spec. -- |
