Crash while updating the query pipeline

[sconybeare]

Running this example with debug asserts enabled crashes with an integer overflow during the call to state.step() while the query pipeline is updated.

The panic message is:

Confirming this, and it also applies to parry3d since (I think) 0.13.

[wlinna]

This happens to me with 0.13.0 in my application. Update runs for minutes, and then finally crashes with this same error in the same line of code.

Just hit this in parry3d-f64 0.13.5.
