Description:
------------
here's a method in an object:

public function setTilePath($path)
{
  $bgimage = imageCreateFromPNG($path);
  ImageSetTile($this->imgHdl, $bgimage);
} 
that tile is used elsewhere in a different method later

in 5.2, this works. in 5.3, it only works if I amend it to be:

public function setTilePath($path)
{
  $this->bgimage = imageCreateFromPNG($path);
  ImageSetTile($this->imgHdl, $this->bgimage);
} 

I spoke briefly about this with Pierre online, I'm pookey on freenode if anyone wants to talk to me about it.

Reproduce code:
---------------
author is very lazy, no reproduction code I'm afraid.

Expected result:
----------------
I expect it to work despite going out of scope

Actual result:
--------------
It doesn't work, broken, fail, no image, unhappy coder.
