Yes it works some way but may not be correct solution. In this case the alignment may be just for some performance reason but somewhere else it really must be 16 (e.g. SSE?) and then 8 would not be OK. So use rather _mm_alloc - well' I didn't check the pointers if they are really aligned but should be, it seems use malloc, align the pointer by mask and store original pointer for free () call.
