Comment (by zimbatm):

 Ok, apparently OSX seems to be 16-byte mem aligned [1]. If I turn
 HAVE_POSIX_MEMALIGN in the config.h, then the error disappears but I don't
 really understand the implications of this, it's a bit too low-level for
 me. I tried hacking the ./configure script to disable posix_memalign on
 darwin, but the have_func check is run after the platform-specific checks.
 What else could I try ?
