Description:
------------
Word alignment problem in apc_sma.c causes bus error.



Reproduce code:
---------------
<?php
phpinfo();
?>

In release 1.53, a pad element to ensure structure header_t is aligned was added.

In release 1.54, a new element was added in the structure which makes the padding added in release 1.53 useless and now causes structure to no longer be aligned.

Patch is provided below:
