I have the same problem in an application of my own. As soon as I try to rotate something using the Manipulation events, I randomly get AccessViolationExceptions. Was not able to figure this out, it seemed to come from within Unity, and not my code. Hopefully its just a bug in Unity. @nash what version of Unity are you using?

Are you getting any sort of an error in the debugger? Post your manipulation code. Did you just copy/paste, or did you make some modifications?
@nash thank you reporting this issue. Looks like a regression in the product code base. We are working on getting a bug filed and tracking this issue.
I got the same problem in Unity when I switch navigation to manipulation using keyword. After few seconds of manipulation. The application crashed.
@neerajwadhwa I am working on a capstone project and manipulation is critical for my project. Is it possible to get this fixed soon? Or is there anything else I can rely on?
Thanks
Is it possible to just try catch this exception?

Please let us know if you're still seeing the issue after updating.
For those unable to update just yet (not wanting to introduce potential new issues/etc) you can get around this by not having your update function call SendMessageUpwards("PerformManipulationUpdate"...) and instead have the object that is waiting for the update grab the ManipulationPosition on its update tick. Note: This may not work for navigation as the position there is not absolute.
EDIT: Nevermind, it still crashes when trying to move the object during manipulation updates. Just not scaling for some reason.
