I believe there is a double free here that causes a crash.

The delete in ContactPair destructor causes a crash. (i believe the SDK will also try to free it after finish calling OnContact callback?)

Yeah sounds about right, especially seeing as the PxContactPair variable is passed in to the constructor as opposed to being created in it
