That's exactly the issue I am referring too. Under Delphi the temporary
interface reference gets freed only when the interface goes out of scope
- example when a procedure/function block ends. FPC I believe frees the
temporary interface reference immediately (or something undefined - I
can't remember).

Even though the "freeing of a temporary interface" is not documented in
Delphi per se, its behaviour has been consistent for over a decade.
There are even 3rd party products based on that behaviour (Raize
CodeSite extensions etc). So even though it is not documented, it's
behaviour is well known, understood and has always been consistent, no
matter which version of Delphi you use.

But yes, I understand the FPC developers point of view too.
