After week I decided to do some more info, maybe it could help:

I can reproduce error on shaka demo content - I added manifest to issue.

I also updated to new version to try fix you added few days before, but it didn't helped.

If I prevent aborting app after this error, app still crash due to memory - Terminated due to memory issue. So it seems like some infinity loop appears.

More to reproduction:
I don't wait until content is loaded. I interrupt previous load with new one. App crash after some try tries, most likely if I do load in specific step of previous buffering.

In our app users can seek in time. On each seek, we do load and play specific manifest. So there error is critical because of app crash.

Thanks for any help

I finally found way how to reproduce error:
When I call load() method in situation, that video from previous load() has been loaded and .play() was called but audio still not playing.
In this occasion, app crashes always.

I updated title of issue and reproduction step in main description.
