I wasn’t sure what the order of class constructors/destructors was with respect to initialization/finalization sections. [WayBack] Class Constructors. Popping the hood. – Community Blogs – Embarcadero Community explains that there is more to it than below summary, but it is a good start:
If a given class constructor is eligible to be invoked (ie. it was linked into your application), it will run immediately before the initialization section for the unit in which the class is implemented. The class destructors will be invoked immediately after the finalization section for the unit in which the class is implemented.
