Burst error BC0102: Unexpected internal compiler error

Accidentally ran into an internal burst compile error while refactoring some code.

Error

Simple repo code

Code (CSharp):

1. public struct TestData
2. {
3.     public int3 Min;
4.     public int Size;
5. }
6.  
7. [BurstCompile]
8. private struct Repo : IJob
9. {
10.     public NativeReference<TestData> Root;
11.  
12.     public void Execute()
13.     {
14.         this.FailMethod((TestData*)this.Root.GetUnsafePtr());
15.     }
16.  
17.     private void FailMethod(in TestData* node)
18.     {
19.         var aabb = new Unity.Mathematics.MinMaxAABB { Min = node->Min, Max = node->Size };
20.     }
21. }

The issue is just the

Code (CSharp):

1. in TestData* node

Removing the 'in' and burst compiles fine.

This is a pretty irrelevant bug as the 'in' doesn't do anything on a pointer as far as I'm aware, I was just refactoring a method and accidentally left it on.

Only reporting it just because as far as I'm aware this is technically valid code and the repo was very simple.
