I'd say that the entire concept of octal literals is a bug, yes. (It's almost _entirely_ useless, a leftover from the days of yore. When for Christmas, we got naked, wrapped ourselves in punch tape versions of the latest "editor", and danced around the Christmas tree while setting the line printer on fire. But I digress.. ;)
But fine, if I at least got "undefined" (well, null) as a result of parsing an invalid octal string, it'd be not quite as bad. So yes, if we talk root causes, you put your finger on that. The anachronism of octal parsing just exposes it.
