That would be a bad idea since it would break standard conformant programs which only override the default operator new. You are implicitly assuming that we know the alignment of memory returned by new. If we know that, then whenever we need aligned memory, we can ask for a bit more memory and force the alignment. That will always work and avoids the concerns of overriding new. We can generate more optimal code by providing a command line option which specifies the alignment of memory returned by new. Ian
