The conduct of arrays is undefined inside the existence of destructors that toss due to the fact there is no affordable rollback behavior that would at any time be devised. Just think: What code can the compiler produce for constructing an arr in which, if the fourth item’s constructor throws, the code has to give up and in its cleanup manner attempts to phone the destructors of the already-produced objects … and a number of of These destructors throws? There isn't a satisfactory response.
