I suspect the `alignof' > procedure is my friend here, but I don't understand how to use it. The ‘alignof’ procedure was actually your enemy here. ;-) This patch should fix it (will be in 2.0.1): http://git.savannah.gnu.org/cgit/guile.git/commit/?h=stable-2.0&id=d82f8518b96bbfa4f29e03d922369c37b64824d9 Thanks!
