Description:
------------
the set_error_handler() seems to not working correctly with E_STRICT notices.

relevant changes to php.ini:
error_reporting  =  E_ALL | E_STRICT
display_errors = On
display_startup_errors = On

Reproduce code:
---------------
class sfc_error {
  function __construct() {
    set_error_handler(array(&$this, 'handler'), E_ALL | E_STRICT);
  }

  function handler($errno, $errstr, $errfile, $errline, $errctx) {
    //log the error
  }
}

Expected result:
----------------
My class should intercept every error and log them.

Actual result:
--------------
All the errors are intercepted, except the E_STRICT ones, which are displayed (sent to the HTML output) as if my handle routine was bypassed.
