I am a little shocked by your arguments because that kind of bug is possible since we have initialization/finalization section and uses section in interface/implementation section. *The programmer must be aware of*. The mentioned bugs are here a looong time. For example fixed by me for Lazarus: http://svn.freepascal.org/cgi-bin/viewvc.cgi?view=revision&root=lazarus&sortby=date&revision=49547 >
That might be, but this just adds a new category of possibilities for such bugs and that is something that we should not do, especially one as subtle as this. One possible solution would be to disallow records with management operators for global variables (variables created for Default() might be an exception here, but I'd need to think that through).
