i never saw anything about a change to call_user_func_array as you describe
in php5.3 moreover a quick test shows its working as expected, namely when
the first argument of the callback array is an object, not a string naming a
class.
<?php
echo phpversion() . PHP_EOL;
class A {
function b() {
var_dump(__METHOD__);
}
}
$a = new A();
?>
5.3.0
string(4) "A::b"
