Attached is a sample application reproducing the problem. Compile the

no interface reference is ever returned.
Yet more testing..... Now I've managed to get it to work in all FPC
versions. Yeah!!!
If I change my class that does interface delegation to the following syntax:
TClassA = class(TObject, ICmdLine)
private
FCmdLineParams: TCmdLineImpl;
function GetCmdLineParamsInterface: TCmdLineImpl;
property ChildDelegate: TCmdLineImpl read GetCmdLineParamsInterface
implements ICmdLine;
public
destructor Destroy; override;
end;
Then it works. Note I changed the function and property definitions.
Still strange that FPC 2.6.4 worked in my prior example and FPC 3.x not.
I also didn't see any "User Changes" on the wiki about this changed
behaviour of Interface Delegation.
