Subject: [PATCH] lua.c: fix ZSTR_VAL usage when using lua < 5.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When using a lua interpreter with a version lower than 5.1, the
php_lua_write_property ends up calling the ZSTR_VAL with the wrong
variable (it is expected to receive "member", a zend_string variable,
but it is "value" that is passed, which is a zval).

Fix php-lua compatibility with interpreters < 5.2 by passing the correct
variable

Upstream: upstream dead, custom patch
