We saw that the pointer has a hard 16 byte alignment requirement since the compiler uses SSE instructions to zero the memory in some circumstances. </p><p>Does the C++ standard require that alignment?</p><p>I read that both Linux and Windows malloc return a 2*sizeof(void*) alignment, so maybe we're the first that notice that requirement.</p><p>Regards,<br>Bernhard<br></p></body></html>
