Actually, no ... it's still after main(), and the constructors run before.
So I _think_ with the CONFIG_CONSTRUCTORS revert, this will no longer work (but happy to be proven wrong!), if so then I guess we do have to find a way to initialize the KASAN things from another (somehow earlier?) constructor ...
Or find a way to fix CONFIG_CONSTRUCTORS and not revert, but I looked at it quite a bit and didn't.
