I don't know why you do not get the error. But I know the reason for the
bug. The finalizaton sections of synedit are executed before the
finalization of forms.pp. This is ok under Delphi and it should also be ok
under the lcl. But when a program shuts down Delphi quits/kills all
components and after that the program ends and the finalization sections do
their work. The lcl does not yet support this clean shutdown and therefore
shuts down the components when the forms.pp is finalizing. So, the synedit
units are closed before the synedit components are closed.
The "bug" exists for a long time. I did not fix it because my priority is
on a starting and running IDE, not on a closing one.
