Hm... so FPC class constructor (or class initialization) works like unit
initialization.

Thanks for sharing this information.

It's hard to make test-case when the code has an extensive use of
initialization sections, so currently I'm avoiding it too. However, I need
to register some classes in a class list, so I'm changing my code to do it
in some place like application initialization.
