StackOverflowException error is thrown when K-D Tree is generated

Mono

-

How to reproduce:
1. Open attached project ("StackSize.zip")
2. Open SampleScene scene
3. Enter Play mode
4. Exit Play mode
5. Build and Run project

Expected result: No StackOverflowException is thrown
Actual result: StackOverflowException is thrown in the Scene but not in Build

Reproducible with: 2019.2.12f1, 2019.3.0b10, 2020.1.0a12
Not reproducible with: 2017.4.34f1, 2019.1.0a1 (Error in MONO Scene and Build, IL2CPP works without errors), 2019.2.0a2 (Error in MONO Scene and Build, IL2CPP only in Scene)
Note: Error is thrown in both IL2CPP and MONO scripting backends

    Resolution Note (fix version ):

    The code raises a StackOverflowException with a call stack 1000 levels deep. We do use operating system defaults for thread stacks. It is unlikely we will increase the main thread stack space. I would suggest using a non-recursive algorithm or doing the calculation on a non-main thread where you create it with a large enough stack space.
