There was a problem hiding this comment.
This looks like a correct fix. But I'd like us to get an issue logged around this, as this seems like a pit of failure here.
In particular, since Array is "untyped" and due to how new[] {...} works, it means that users can get into these types of silent failures; when they likely expected it to be implicitly typed as double[] like [...] would've been.
So I think we may want to consider if this should be a constructor or instead some named Create* method where * is an appropriate suffix.
