I configured Emacs with:
env CC='cc' CPPFLAGS='-DENABLE_CHECKING' MAKE='gmake' \
./configure --prefix="$HOME/opt" --without-x
On FreeBSD 7.0-CURRENT (amd64) with -DENABLE_CHECKING and the current
posix_memalign(), the build crashes repeatably with:

When I disable posix_memalign(), no assertion is triggered, even with
-DENABLE_CHECKING.
