New Crash in 0.0.12-preview.32 of Entities

Unity Engine

Apologies if this is the wrong place to post this!

It seems like today’s update to the Entities package has introduced a crash in ```
EntityManager.AddComponent(NativeArray entities, ComponentType componentType);


Easily reproducible in preview.32, can't reproduce it in preview.31

Triggering code:

```csharp
                var treesToCheck = new NativeArray<Entity>(filteredIndices.Length, Allocator.TempJob);
                result = new BuildArrayJob
                {
                    UnfilteredEntities = uncheckedTrees,
                    FilteredIndices = filteredIndices.AsArray(),
                    FilteredEntities = treesToCheck
                }.Schedule(filteredIndices.Length, 8, result);
                result.Complete();

                // Mark all of those trees as Checked
                EntityManager.AddComponent(treesToCheck, typeof(Checked));

Do you have a small project folder that reproduces the issue?

3

IJobForeach_B also crashes the unity.

4

Please make a repro project for that as well.

5

I’ll try to put something together on Monday

Sorry this took so long @Joachim_Ante_1 , I submitted the repro project through the Bug Sender, Case 1157047
