Description:
------------
when using imagecopymergegray with pct value of 100, everything is fine, i.e., imagecopymergegray works exactly as imagecopy. but, when setting pct value to 99 or less, apache crashes.

Reproduce code:
---------------
$pic1 = imagecreatefromjpeg("my.jpg"); // 100x100px
$pic2 = imagecreatetruecolor(100, 100);

imacecopy($pic2, $pic1, 0, 0, 0, 0, 100, 100);
imagecopymergegray($pic2, $pic1, 0, 0, 0, 0, 100, 100, 50);

imagejpeg($pic2,"my2.jpg");
imagedestroy($pic2);


Expected result:
----------------
my2.jpg - slightly saturated version of my.jpg.

Actual result:
--------------
a crash.

Works fine for me. If you can provide the image you tried with, that would help a lot. Also the configure line you used to configure PHP helps.
