[libcamera-devel] [PATCH 07/12] test: message: Destroy Object from correct thread context

[Laurent Pinchart]

The MessageReceiver and RecursiveMessageReceiver used in the test are
destroyed from the main thread, which is invalid for a thread-bound
object bound to a different thread. Fix it by destroying them with
deleteLater().
