Problem with IJobParallelForDeferExtensions after upgrade to 2021.2.8f1

My project was running happily under 2021.2.5f1 before I then upgraded to 2021.2.8f1. With the new version there seem to be major issues in a couple of jobs, one my own, the other within Unity Physics. In both cases it seems there are errors related to use of IJobParallelForDeferExtensions.

Here are the callstacks:

IndexOutOfRangeException: Index 4032 is out of range of '0' Length.
Unity.Collections.NativeArray`1[T].FailOutOfRangeError (System.Int32 index) (at <15e405c9beda435fb78db5a973118bc4>:0)

Anyone else seen anything like this? Any ideas what could be at fault?

For now, I reverted to 2021.2.5 and everything is running fine again...
