startImageTask causing memory issue and crashing the app

[jcbriones]

This function is crashing the app. Not sure what has changed but there's a lot of crashes from time to time with the following function

   private func makeStartedImageTask(with request: ImageRequest, isDataTask: Bool = false, onEvent: ((ImageTask.Event, ImageTask) -> Void)? = nil) -> ImageTask {
        let task = ImageTask(taskId: nextTaskId, request: request, isDataTask: isDataTask, pipeline: self, onEvent: onEvent)
        // Important to call it before `imageTaskStartCalled`
        if !isDataTask {
            delegate.imageTaskCreated(task, pipeline: self)
        }
        task._task = Task {
            try await withUnsafeThrowingContinuation { continuation in
                self.queue.async {
                    task._continuation = continuation
                    self.startImageTask(task, isDataTask: isDataTask)
                }
            }
        }
        return task
    }

Hey, could you please share a bit more details, including a crash log and the OS version.

[jcbriones]

I'll send it over once I got more details as well.

[hfabisiak]

I've also encountered the same issue

[jcbriones]

I don't know what else I can share about this but it looks like it's happening mostly on when an image begins to load and either the view that was loading the image change let's say the view got removed then it crashes. But not always though. Seems like a race condition issue as well

[kean]

I hope this will be addressed by #802. It now fully switches to actors, so there won't be any opportunities for race conditions in the pipeline. I plan to ship a beta soon.
