OnCollisionEnter() crash with IL2CPP on iOS

Hello,

With 4.6.7, 4.6.7p1 or 4.6.7p2 , Unity crash on iOS if I use OnCollisionEnter() with IL2CPP Scripting Backend.

void OnCollisionEnter(){
blablabla
}

Works fine with Mono 2.x Scripting Backend.

The workaround is to use OnCollisionEnter(Collision obj)

void OnCollisionEnter(Collision obj){
blablabla
}

Try use unity 5
