 New Comment:

It is weird, nothing in the imagefill code changed between 5.2.4 and
5.2.5RC.

Can you provide a backtrace please?

Description:
------------
Filling an image with a pattern causes httpd segmentation fault.  It is

reproducible, but it does depend on the image dimensions.  Version
5.2.3 
works fine, so something changed as of 5.2.4, and still fails in 
5.2.5RC1.

Reproduce code:
---------------
$im = ImageCreate( 200, 100 );
$black = ImageColorAllocate( $im, 0, 0, 0 );

$im_tile = ImageCreateFromGif( "transback.gif" );
ImageSetTile( $im, $im_tile );
ImageFill( $im, 0, 0, IMG_COLOR_TILED );

header( "Content-type: image/gif" );
ImageGif( $im );
ImageDestroy( $im );

Expected result:
----------------
A 200x100 image filled with the specified pattern.  

BTW, the pattern itself is unremarkable, it fails with several
different 
files I've tried. transback.gif above is a 64x64 from 
http://www.blueknot.com/CSS/TRANSBACK.gif

If you change the image dimensions to 100x100, it will work.  101x100 
does not!

I've also made it fail using gdImageFilledRectangle and particular 
rectangle dimensions to fill, but was unable to find a correlation. So

the code above is the simplest example of the failure.

Actual result:
--------------
Safari reports the server suddenly dropped connection.  Running httpd 
-X 
yields "Segmentation fault" when I execute the above script.

Even though I followed the instructions to the letter and tried both 
httpd -X and through gdb, I am unable to produce a core dump or 
backtrace...sorry.  (The gdb method fails immediately upon startup 
with 
"gdb in realloc(): error: pointer to wrong page" but I believe that is

unrelated because 5.2.3 also gives me that error when I attempt to run

it through gdb),

My server is a practically fresh FreeBSD 6.2 install, and I'm using 
the bundled GD library.  This is my configuration command:

./configure --with-mysql --with-mysqli --with-
apxs=/usr/local/apache/bin/apxs --with-gd --with-zlib --with-png-
dir=/usr/local --with-jpeg-dir=/usr/local --enable-debug
