Description:
------------
ext/enchant/tests/bug13181.php triggers an unaligned memory access in
enchant.c's enchant_dict_suggest().

enchant_dict_quick_check() is also affected, so adding a test case (the
one from the documentation but simply count()ing the returned array for
>0, for example) is a good idea.

Attached patch fixes the first case.


Expected result:
----------------
resource(5) of type (enchant_dict)
resource(5) of type (enchant_dict)
resource(6) of type (enchant_broker)
resource(6) of type (enchant_broker)
resource(7) of type (enchant_dict)
resource(7) of type (enchant_dict)

Actual result:
--------------
resource(5) of type (enchant_dict)
resource(5) of type (enchant_dict)
Bus error
