Concurrent NativeQueue crash

Hello, I started playing with ECS & Job system and I'm facing an unity crash.

I have a simple Job that hash positions in an hash map and stores keys into a concurrent NativeQueue.

It works as expected with a NativeList cast to a NativeArray thanks to ToDeferredJobArray(), but when I tried with a NativeQueue each attempts crash.

Here's the job.

Code (CSharp):

1.  
2. [ComputeJobOptimization]
3. struct HashPositions : IJobParallelFor
4. {
5.     [ReadOnly] public ComponentDataArray<PositionByte> positions;
6.     [ReadOnly] public ComponentDataArray<Status> status;
7.  
8.     [WriteOnly] public NativeHashMap<ulong, PositionByte>.Concurrent hashMap;
9.     [WriteOnly] public NativeQueue<ulong>.Concurrent keys;
10.  
11.      public void Execute(int index)
12.       {
13.           if (!status[index].IsVisible() || !status[index].IsAlive())
14.               return;
15.  
16.           var hash = HashUtility.Hash(positions[index].GetFlattenIndex());
17.           hashMap.TryAdd(hash, positions[index]);
18.           keys.Enqueue(hash);
19.       }
20. }

And this is how I call my job on the main thread.

Code (CSharp):

1.  
2. var positions = m_VolumeGroup.GetComponentDataArray<PositionByte>();
3. var status = m_VolumeGroup.GetComponentDataArray<Status>();
4. var hashMap = new NativeHashMap<ulong, PositionByte>(positions.Length, Allocator.TempJob);
5. var keys = new NativeQueue<ulong>(Allocator.TempJob);
6.              
7.  var hashPositionsJob = new HashPositions()
8.         {
9.             positions = positions,
10.             status = status,
11.             hashMap = hashMap,
12.             keys = keys
13.         }.Schedule(positions.Length, 32, inputDeps);
14.  

Any idea of what I'm doing wrong ?

 

Ok, it seems that this is the [ComputeJobOptimization] attribute which crashes my editor.

I removed it and everything works fine.
