Collab and debugallocator do not work together on 2017.1

1. What happened

On both staging and prod, 2017.1 crashes when attempting to use collab after you've started Unity with command line -debug allocator argument. An error is thrown to my console on crash, "Segmentation fault". See screenshot.

2. How we can reproduce it using the example you attached

1. Start Unity with argument -debugallocator
2. DL some content from the asset store (I used the Sebastian model from the Adam series)
3. In the services window, enable collab and attempt to sync
4. Observe crash.
