Crashes galore on theme change about delphi-event-bus HOT 4 CLOSED

Hello Steve, what post mode are you using?

from delphi-event-bus.

I am also using vcl styles and my application doesn't crash on design changes. Since your application crashes on design changes, I assume that you are still subscribed to events during the re-creation.
I'd recommend that in every create/destroy pair the last thing you do in the constructor is to subscribe to events and the first thing in the destructor is to unsubscribe from events.

I agree with @luebbe . EventBus should not conflict with the VCL styles as I cannot see any relation. Going to close the bug but if @SwiftExpat you can create a demo demonstrating the issue I will reopen it

I say close it.

Without a minimum sample from the poster I do not know what I would re-create ( I have an idea but far from a use case ). I never got a reply on the post mode but my guess is it crosses a thread boundary: the event fires on the producer possibly and is received by main.

Technically the question to be answered is does the subscribed procedure have the same address after re-creation? The other question is are there tasks in process while the recreation takes place.

To figure out my own issues I wrote a FMX demo app here my fork, deb overflow which simulates a "busy app", multiple threads producing events and slowly processing the events.

There are limits to DEB, especially in the tasks, but it is case by case. I can break anything and then learn how to code around it.
