Bug description: call_user_func_array disrespect returned references
Description:
------------
Unfortunatly even in version 4.3.3 there was an bug with
"call_user_func_array" function.
call_user_func and call_user_func do respect functions that return
references. That is, function foo that returns a references to an
object, does not return a reference to an object when foo is called via
call_user_func. Instead, foo called via call_user_func returns a "copy"
of the object. (I'm not sure "copy" is the right word.) See the code
example for a concise example of the problem.
Reproduce code:
---------------
function &testfunction()
{
global $testglobal;
return ($testglobal=1);
}
$testglobal_link=&call_user_func_array("testfunction",array('testparam-1','testparam-2'));
// $testglobal_link must be link to $testglobal at this stage
print $testglobal_link;
// trying to assign new value to $testglobal thru link
$testglobal_link=2;
// in theory we will get "2" as result
print $testglobal;
// but unfortunatly we will have "1" as result
print $testglobal_link;
