Hi Felipe, you are probably using version >=5.3. This bug related to
version below 
5.3 and it was reproduced on server running 5.2.13

I cannot reproduce this.

I got the message "Warning:
call_user_func(experimental::non_existing_method): First argument is
expected to be a valid callback"

Description:
------------
I have discovered weird call_user_func behaviour while calling non
existing method 
of the class. Instead of throwing some type of warning it tries to call
non 
existing class with scrambled name.


Test script:
---------------
<?php
class experimental{}

function __autoload($class_name)
{
	echo sprintf('<pre>%s</pre>',print_r(debug_backtrace(),true));
}

call_user_func(array('experimental','non_existing_method'));
?>

Expected result:
----------------
some king of warning or error

Actual result:
--------------
Array
(
    [0] => Array
        (
            [function] => __autoload
            [args] => Array
                (
                    [0] => zybplbn6ps6m
                )

        )

    [1] => Array
        (
            [file] => /www/test.php
            [line] => 13
            [function] => call_user_func
            [args] => Array
                (
                    [0] => Array
                        (
                            [0] => experimental
                            [1] => non_existing_method
                        )

                )

        )

)
