Fix segv with AES-NI on some platforms.
* cipher/rijndael.c (RIJNDAEL_context): Align on 16 bytes.
--
The trigger for this problem is the allocation of the context in the
selftest functions. The other code paths use a 16 byte alignment
anyway by means of the allocation of the context in cipher.c
Thanks to Gentoo hacker Joakim Tjernlund for figuring out the reason
of this problem.
