Hello,
In testing upcoming 2.0.4 release i found an incompatibility/memory
leak which is present in fpc versions greater 2.0.2.
I tested faulty against
2.0.3 fixes svn
2.1.1 head svn
2.0.4 rc2 branch svn
Working OK with 2.0.2 Release.
The following code runs differently on compiler versions greater 2.0.2
function TTestCollection.Add(const
Item:IInterface): Integer; begin
FList^[0] := Item as IInterface; // (1)
//FList^[0] := Item; // (2)
end;
(1) => Original Code No Memory Leak with FPC=2.0.2 but with > 2.0.2
(2) => No Memory Leak
Reported with a demo program as Bug 7174.

I post this to the list, as i spent the whole night on searching this
bug
and maybe it helps someone out.
Greets,
helmut
