http://d.puremagic.com/issues/show_bug.cgi?id=5637 Summary: Anonymous structs/unions should have their own context Product: D Version: D1 & D2 Platform: All OS/Version: All Status: NEW Severity: major Priority: P2 Component: DMD AssignedTo: nobody puremagic.com ReportedBy: ibuclaw ubuntu.com This is kinda in the same league as bug1432, and I'm pretty certain fixing this will fix the other bug too. Basic example to show what I'm talking about: union A { double d; struct { uint hi; uint lo; } } Here, DMD reports that the union has 3 members, this is IMHO a bogus analysis. The union has 2 members, and one of them is an anonymous structure who is also the parent/context of the two fields (hi, lo) that it encases. This particular example also hurts GDC in some instances, as having a member of a *union* to whom's offset is > 0 confuses the backend. But there is currently no way/information available at the codegen stage to prevent this; except, perhaps looking ahead to scan the offset of all union members to see if the frontend is hiding a structure somewhere. This is less than ideal though, and would be better if there was anything to work with.
