You can probably force do the same thing as malloc() from glibc does and
use a default alignment of 8 for 32bit and 16 for 64bit platforms:

   Alignment: 2 * sizeof(size_t) (default)
        (i.e., 8 byte alignment with 4byte size_t). This suffices for
        nearly all current machines and C compilers. However, you can
        define MALLOC_ALIGNMENT to be wider than this if necessary.
