Are you saying that glibc malloc does not return blocks that are
sufficiently aligned? My copy of the glibc manual says:
The block that `malloc' gives you is guaranteed to be aligned so
that it can hold any type of data. In the GNU system, the address
is always a multiple of eight on most systems, and a multiple of 16
on 64-bit systems.
