This is true, however relevant only if your extension uses low-level Zend engine functions for case-insensitive string comparison, and you're not using zvals, and you require this comparison to depend on current locale. This is pretty exotic use case unless you're reimplementing strcasecmp(). > You also change the behavior of zend_binary_strncasecmp().

That's kind of the point of the fix - to change the behavior (which previously depended on current locale and thus produced wrong behavior). -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227
