Deepti - Clusterfuzz found a place where ArrayBuffers get neutered twice in Chrome! I'll investigate this today.

This issue is ultimately due to a spec inconsistency: https://github.com/tc39/ecma262/issues/1024

It's slated to be discussed at the TC39 meeting next week. Because this is a safe crash (CHECK, rather than some rogue memory access), I think we should wait and see what the outcome of TC39 is and then fix it according to the spec.
