Returning NativeList from a method

It seems that NativeList forgets it's allocator type when it is being returned from a method. When debuger breakpoint is set inside the method and I inspect the list I see this:

After I exit the the method and inspect returned value I see this:


m_AllocatorLabel is now Invalid and when I try to Dispose the list I get:

Code (CSharp):

1. InvalidOperationException: The NativeArray can not be Disposed because it was not allocated with a valid allocator.
