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.

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.
