Bug description:  ImageCopyMerge doesn't work in 4.3.2

Description:
------------
ImageCopyMerge doesn't work in PHP 4.3.2. It seems as though the source
image is ignored and instead a black image is used for merging the colors.
The same script works in PHP 4.3.1 as expected.

Reproduce code:
---------------
$img = ImageCreateTrueColor(100, 100);
ImageFill($img, 0, 0, ImageColorAllocate($img, 255, 255, 255));

$img2 = ImageCreateTrueColor(50, 50);
ImageFill($img2, 0, 0, ImageColorAllocate($img2, 0, 0, 0));

ImageCopyMerge($img, $img2, 0, 0, 0, 0, 50, 50, 50);

ImagePNG($img);


Expected result:
----------------
A gray box. (50% black)

Actual result:
--------------
A black box. (100% black)
