OverrideController switching crashs unity starting with 5.6.1p4

Unity Engine
1

Ever since Patch 5.6.1p4 unity is crashing after about 30 secs in our game. It seems to be related to our use of override controllers. This also occurs in 5.6.2f1

I have filed this as case 923813, but my project is too big to upload. But I would be happy to provide it privately.

This is the exception that unity crashes with.

Exception Information: The thread tried to read from or write to a virtual address for which it does not have the appropriate access.

Here is the stack trace.

This happens in 5.6.2p1 too. I was contacted by someone in test to provide a private build which I did.

This is still happening in 2017.1.0f3

I hope someone can look at this, it has been nearly a month since I reported this, and this hasn’t been confirmed yet. We are stuck on 5.6.1p3 because of this.
