Forgot to mention a record or object with at least one method will get to
the first part also, but never the FreeInstance part as they can never have
destructors.

You need to declare a class, and give that class at least one

Doing a quick search for the word "freeinstance" in the compiler source
shows two places where it looks for a member function with that name in the
global "current_structdef" variable. I'm fairly certain the one you're
looking for is in a function

I’m still trying to find this with no luck. I suspect there’s a call node added
when the compiler detects a destructor was called (maybe in

then how does it get invoked then? there

Looking at the FPC source now and it appears FreeInstance is a hidden method
which is not called from the TObject destructor.
