The following script(s) cause an internal compiler error:

----------------- foo.php -----------------
<?php

namespace foo
{
    class bar
    {
        function __construct()
        {
            require_once 'include.php';
        }

        function _debug()
        {
            print $baz;
        }
    }

}

$foo = new foo::bar();
$foo->_debug();

?>

----------------- include.php -----------------
<?php

function fakefunc()
{
    $baz = 'I am foobar!';
}

?>

-----------------------------------------------

Running foo.php via CLI causes the following fatal error to occur:

*Fatal error:  Internal compiler error.  Please report! in include.php on line 6*

Running the script without the 'foo' namespace simply outputs a blank line to the console, with no text returned, and no error generated.
