Bug description:streamwrapper/stream_stat causes problems

Description:
------------
I experienced odd things testing code that was working with 5.2.19.

It look like reading a file with file_get_contents using a streamwrapper
class 
destroys some part of the zend engine. After reading the file all sorts of
odd 
problems occur.

I tracked it down to undefined variables returned by stream_stat() in my
stream 
wrapper class. Casting the values to an integer fixes it.





Test script:
---------------
class StreamWrapper {
  public function stream_stat() {

    return array(
      'atime' => $this->notset,
      'mtime' => $this->notset,
      'ctime' => $this->notset,
    );

  }
}
