It looks like `intern` was called with a second argument that wasn't of a valid type (obarray or nonempty vector starting with 0) but that's as far as it goes, and doesn't indicate anything wrong in the obarray code.

We would need to catch it in the act with a debugger attached, and/or know what Lisp code is being executed.
