IMO this is not my case. As I see in your patch these lines are about 
property setter "procedure Set_..." but I have error in "INVOKE_FUNC" 
branch (about line 640-650) ...
There is:
           if bParamByRef then
             case FD^.lprgelemdescParam[k].paramdesc.wParamFlags and 
             PARAMFLAG_FIN or PARAMFLAG_FOUT:sPar:='var ';
             PARAMFLAG_FOUT:sPar:='out ';
             PARAMFLAG_FIN:sPar:='var '; //constref in safecall? TBD
In my case bParamByRef = True, but wParamFlags=0 so no "var" nor "out" 
is added ...
(as I do no known about type libraries I fear, that any modification 
which fixes my case can cause problems in another cases)
So I have posted bug report: 
http://bugs.freepascal.org/view.php?id=30764 may be somebody experienced 
can fix it ...
