The assumption that this bug is fixed because it could not be reproduced is incorrect. I can reproduce it on any clean Delphi installation with a set of my source code.

It occurs on this line of code:

IObserver(FBoundObject).DetachAll;

Normally this compiles just fine, but in certain environmental situations the compiler generates an E1513 and I waste a great deal of time trying to figure out why so I can move onto some real work.

I agree, the same problem happens to me. In my case, I have a interfaced object that uses delegation implemented and deployed in a package that is used by another one. Maybe it´s a module boundary problema, but it certainly exists and causes a big trouble.
