So the problem is either in the implementation of posix_memalign, or in my
use of it in src/alloc.c.

Can you try and rebuilt with -DENABLE_CHECKING so as to activate the
`eassert' I have sprinkled in the src/alloc.c code?

Just to be sure, try with -DENABLE_CHECKING for both cases (with and
without HAVE_POSIX_MEMALIGN).

Since Emacs's posix_memalign code has already been used for more than a year
under GNU/Linux and probably more platforms, I'm tempted to say the bug is
in FreeBSD's new implementation.  But you never know.
