Bug #51289 [NEW]: unaligned memory access in enchant.c
From: geissert
Operating system: linux ia64
PHP version: 5.3.2
Package: *Spelling functions
Bug Type: Bug
Bug description:unaligned memory access in enchant.c
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
