Something I've queried with the FPC developers some 10 years ago. The 
Delphi behaviour is undocumented, so developers are relying on a 
implementation detail that could change without notice.

FPC, as you noticed, implements such behaviour differently. They can, 
because once again, the Delphi behaviour in undocumented.

As someone that also works on Delphi code, the "cool interfaces trick" 
so often used in Delphi (eg: to implement a home-grown call stack etc) 
doesn't work so nicely with FPC - where you need a interface reference 

Anyway, the FPC team had no intention in changing the behaviour to 
something that is undocumented. So we had to learn to live with it. 
Maybe you have more luck with them that I did. ;-)
