Bug description: Reference argument converted to value in __call
Description:
------------
This is a regression in the PHP 5.3.1 release. When you call a __call()
function with a reference parameter, it is silently converted to a value,
by the time it reaches the second argument to __call().
This breaks MediaWiki and has no obvious workaround.
Reproduce code:
---------------
function foo( &$x ) {}
class Proxy {
function __call( $name, $args ) {
debug_zval_dump( $args );
call_user_func_array( 'foo', $args );
}
}
$arg = 1;
$args = array( &$arg );
$proxy = new Proxy;
call_user_func_array( array( &$proxy, 'bar' ), $args );
Expected result:
----------------
PHP 5.3.0 produces:
array(1) refcount(4){
[0]=>
&long(1) refcount(5)
}
Actual result:
--------------
array(1) refcount(4){
[0]=>
long(1) refcount(3)
}
Warning: Parameter 1 to foo() expected to be a reference, value given in
