You can't if you compile with -CR.
The RTL is not compiled with objectchecks, so it works there.

I never use Free directly so I had no idea. How is that even accomplished in
the language? I thought it was just a method and behaved accordingly.

You've been able to accomplish your tasks without use of hacks (of any
