[5.5][5.6] Multiple cloth instances cause a crash on scene loading

Physics

-

When loading between scenes, a crash will occur if there are multiple instances of cloth in the unloaded scene.

Reproduction Steps:
1. Build & Run the attached project
2. Press Fire1 (either LMB or Left CTRL) to trigger a reload, repeat until the following message appears (6 times, from my testing):
"PxScene::removeActor(): Actor not assigned to scene or assigned to another scene. Call will be ignored!"
3. Press Fire1 once more, a crash will occur

Alternatively, press Fire2 (RMB or Left ALT) to cause the game to endlessly reload the scene, and it will crash very quickly.

Expected Result:
Unity should not crash when unloading multiple cloth instances.

Reproducible in versions 5.5.0b11 (03364468e96e) and 5.6.0a1 (087280fac800).
Not reproducible in version 5.4.2p3 (466fe82d1f51).

    I have the same problem, and it is causing a scene I worked hard on to crash upon updating to 5.6.1. Every time I load that scene, Unity fails.
