On some systems (though not Linux-based systems) an attempt to free()
results from memalign() may fail. This may, on a few systems, be
exploitable. Also note that memalign() may not check that the boundary
parameter is correct (CWE-676). Use posix_memalign instead (defined in
POSIX's 1003.1d). Don't switch to valloc(); it is marked as obsolete in BSD
4.3, as legacy in SUSv2, and is no longer defined in SUSv3. In some cases,
malloc()'s alignment may be sufficient.
