What's the expected output of this code ?

I thought that when the result type is an automated one its value gets
initialized... Maybe I'm wrong...
Yes you are wrong. It is very illogical because a local string
variable is initialized to be empty but the return value is not.
Delphi has the same problem.
I once made even a report about it:
http://bugs.freepascal.org/view.php?id=20907
That report says the issue was assigned to Jonas and fixed in revision
20427 (ver 2.6.1).
I find the current release (2.6.2) initialises a string function result
to EmptyStr as you would hope.
