My understanding was that using this "feature" would sometimes lead to a crash of the executable. That seems to me to be clearly just a bug.
Even absent that, contrary to the article, I think I'd still call this a bug in bash - but the crash (presuming I'm recalling correctly) makes this position absurd instead of just (IMO) incorrect.
