This file is part of the Free Pascal run time library.
Copyright (c) 1999-2005 by the Free Pascal development team
This unit makes Free Pascal as much as possible Delphi compatible,
defining several internal structures for classes, interfaces, and
resource strings.
Additionally this file defines the interface of TObject, providing
their basic implementation in the corresponding objpas.inc file.
WARNING: IF YOU CHANGE SOME OF THESE INTERNAL RECORDS, MAKE SURE
TO MODIFY THE COMPILER AND OBJPAS.INC ACCORDINGLY, OTHERWISE
THIS WILL LEAD TO CRASHES IN THE RESULTING COMPILER AND/OR RTL.
IN PARTICULAR, THE IMPLEMENTATION PART OF THIS INCLUDE FILE,
OBJPAS.INC, USES SOME HARDCODED RECORD MEMBER OFFSETS.
See the file COPYING.FPC, included in this distribution,
for details about the copyright.

the exception after all, call @link(ReleaseExceptionObject).
Otherwise, if the reference count is > 0, the exception object
goes into your "property" and you need to free it manually.

via "raise;", this zeroes the reference count again.
Calling this method is only valid within an except block.
