This looks good to me.

I trust you know the psABI requirement, so I didn't double check that.

I figure that if malloc/malloc.c (MALLOC_ALIGNMENT) changes to be
below the requirement that this test would trigger a regression?

At present we have ((2 * sizeof(size_t)) - 1) which should be (16 - 1)
and meet the required minimum.

Does that make sense?

Cheers,
Carlos.
