When i an object destroyed (or rather released) when send using Task.Comm.Send()?

Hi,

I send an object from a thread to the main thread like this:

var
U: IUnknown;
...
Task.Comm.Send(MESSAGE_ID, U);

I need to destroy all the objects before the thread ends. Normally, this is not the case: some objects are destroyed after the thread has ended.

I tried Task.Comm.Reader.Empty() and Task.Command.Writer.Empty() but with no success.

How can i force OmniThread to release the objects before the thread ends?

Start by tracing Task.Comm.Send(MESSAGE_ID, U) and the Task.Comm.Reader.Empty() and Task.Command.Writer.Empty() paths, focusing on when the IUnknown reference is released relative to thread shutdown. Determine the expected release point and record or reproduce the behavior; done means the objects are released before the thread ends, or the lifecycle limitation is clearly documented.
