That would only work in fairly simplistic cases. For instance, if you were allocating an array of structs instead of an array of ints, then it _could_ have an effect. So, it's not an error that would catch much. And it's not like the code is doing anything illegal - just useless, which is why it gets optimized out. - Jonathan M Davis
