What advantage does this have over just aligning all the pointers (even to 16-byte to enable movapd and prevent many loads across a cacheline split, see http://x264dev.multimedia.cx/?p=8)?  The arithmetic and few wasted bytes is trivial compared to the cost of the allocation, so I don't see a reason not to.

I think Jed has a VERY good point here... -- Lisandro Dalcín --------------- Centro Internacional de Métodos Computacionales en Ingeniería (CIMEC) Instituto de Desarrollo Tecnológico para la Industria Química (INTEC) Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) PTLC - Güemes 3450, (3000) Santa Fe, Argentina Tel/Fax: +54-(0)342-451.1594
