The habits of arrays is undefined from the existence of destructors that toss since there isn't a sensible rollback behavior that would ever be devised. Just Assume: What code can the compiler produce for setting up an arr exactly where, if the fourth object’s constructor throws, the code has to surrender As well as in its cleanup method attempts to simply call the destructors on the now-produced objects … and one or more of those destructors throws? There is absolutely no satisfactory respond to.
