To Reproduce I have uploaded a sample project.
The crash occurs whenever a message is posted from the main thread to the worker outside the constructor. It is interesting that this does not replicate when posting from the constructor, but at a later date.
I have slightly modified the demo from worker-loader to reproduce the issue when tapping the button.
Expected behavior Application should not crash and worker onMessage method should execute to completion.
