Bug description: Assigning a reference to a reference variable in a function
returns null
Description:
------------
If you pass a variable by reference in a function, then within the
function assign that variable a reference to another variable, the
variable's reference gets overwritten and the variable (when the function
ends) contains null.
Reproduce code:
---------------
$GLOBALS['glob_var'] = 10;
$var = funk($ref_var);
echo 'SHOULD BE 10: '.$var;
function funk(&$ref_var)
{
$ref_var = &$GLOBALS['glob_var'];
}
Expected result:
----------------
> SHOULD BE 10: 10
Actual result:
--------------
> SHOULD BE 10:
