Also by `memalign' I actually mean `posix_memalign' which has no known broken implementation (but is recent and only part of a non-core element of POSIX, so it's missing from several systems). We already use `posix_memalign' actually, when available, to get the multiple-of-1024 alignment used for cons_blocks (I introduced this when I got rid of the markbit). Stefan
