[PHP-INTERNALS] Freeing $1 from zend_language_parser.y

2011/11/18 Clint M Priest <cpriest@zerocue.com>:
Is there any reason I would have to free a pointer from the language_parser if I am just storing a reference to $1

I'm doing this:
CG(accessor_node) = &$1;
This doesn't looks right, as &$1 points to the local variable in yyparse().
And in doing so it is causing a memory leak, only if I add:

efree($1.u.constant.value.str.val);
