Resolution Note (fix version 0.10.0):
The issue here is that all existing ComponentDataFromEntity objects are invalidated when a structural change occurs. In this case, SimpleCdfe is invalidated by the RemoveComponent command played back by ecb.Playback(). SimpleCdfe2, if uncommented, is created after the ECB playback, so it would still be valid in the second ForEach loop.
The error message for this was awful for a long time, as you noticed (what NativeArray? What deallocation?). I'm happy to report that in 2020.1 + Entities 0.10.0 the error message is much more explicit and actionable (it would be something like "The ComponentDataFromEntity has been invalidated by a structural change".
