PHP Bug Type:     SPL related
Bug description:  Inconsistent namespaces sent to functions registered with 
spl_autoload_register

Description:
------------
When you instantiate a namespaced class, the expected behavior is for the
fully qualified namespace with leading slash absent to be passed to your
registered function.  However, if you instantiate a namespaced class with a
class name stored in a variable, the fully qualified namespace is not
evaluated and the leading slash (if specified) is included.

You'll have to run the reproduce code twice to see what I mean.

Reproduce code:
---------------
function loadClass($class) {
    die($class . PHP_EOL);
}

spl_autoload_register('loadClass');

$myClass = '\Fully\Qualified\ClassName';

// run this first:
new \Fully\Qualified\ClassName();

// run this second:
//new $myClass();

Expected result:
----------------
First run:
Fully\Qualified\ClassName

Second run:
Fully\Qualified\ClassName

Actual result:
--------------
First run:
Fully\Qualified\ClassName

Second run:
\Fully\Qualified\ClassName
