The following script crashes and never gets to process anything below
imagecreatefromstring(). When using the same script with a supported
image type (JPG/PNG/GIF/etc.), the script runs fine. Note: The original
script gets $data from a database instead of from a file.

<?php
    $data      = file_get_contents('any-unsupported-image.psd');
    $source_id = imagecreatefromstring($data);
    print_r($source_id);
?>

Here's my configure line:
'./configure' '--prefix=/usr' '--exec-prefix=/usr' '--bindir=/usr/bin'

The Apache error log contains the following error:
[Wed Jan  8 11:46:00 2003] [notice] child pid 25614 exit signal
Segmentation fault (11)

Could you please a provide a sample file that always causes a
segmentation fault?

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

I was able to reproduce same error with php 4.3.4

image used in test: http://www.kodu.net/PICT2029.JPG

simple upload script was used (from tiki-wiki)
<?php
$fp = fopen($_FILES['userfile1']['tmp_name'],"rb");
$data = fread($fp,filesize($_FILES['userfile1']['tmp_name']));
fclose($fp);

//following displayes image correctly in browser:
echo $data;

//this crashes apache thread/php
$img = imagecreatefromstring($data);
?>

My system is up-to-date debian sid (updated 05 aug. 2004).

Also, php 4.3.8 is no better, result is exactly same.
