    What is this supposed to mean?
    System.NullReferenceException: Object reference not set to an instance of an object
    This Exception was thrown from a job compiled with Burst, which has limited exception support.

    My guess is that one of the inputs to the memcpy was a null pointer.

    Yes, it was my mistake but index out of boundary. I was out of my mind posting.

    Any chances that Burst could compile a generic delegate or better, an interface methods?

    Any chances that Unity could provide better static analysis with the C#/HPC# code that deals with anything unmanaged instead of relying on AtomicSafetyHandle/DisposeSentinel?

    "C# first class for developing game, while getting the performance of C++ and more" is a dream, but we need better tools than what we have with current DOTS. One way I could see it is with better native bindings from the engine. Any chances that is happening?
