I have exactly the same problem using Mac OS X 10.4.6, Apache 2 with mod_php (5.2.5), 32-bit. Here is a short script to reproduce the error: ---------------------------------------------- <?php $im = imagecreate (100, 100); $black = imagecolorallocate ($im, 0, 0, 0); imageTTFText ($im, 20, 0, 10, 20, $black, './default.ttf', 'TEST'); imagejpeg ($im); imagedestroy ($im); ?> ---------------------------------------------- You can find the 'default.ttf' I used here: http://www.jtr.de/scripting/php/classes/captcha/index.html (klick "Jax Captcha Class downloaden", you will find the .ttf file in the archive) PHP/the Apache process crashes and I get a 200 Response from the server without any headers or content. Here is what the error log writes: ---------------------------------------------- [notice] Accept mutex: flock (Default: flock) dyld: lazy symbol binding failed: Symbol not found: _FSPathMakeRef Referenced from: /usr/local/lib/freetype-2.2.1/lib/libfreetype.6.dylib Expected in: flat namespace dyld: Symbol not found: _FSPathMakeRef Referenced from: /usr/local/lib/freetype-2.2.1/lib/libfreetype.6.dylib Expected in: flat namespace [Sat Jul 12 17:49:00 2008] [notice] child pid 3369 exit signal Trace/BPT trap (5) dyld: lazy symbol binding failed: Symbol not found: _FSPathMakeRef Referenced from: /usr/local/lib/freetype-2.2.1/lib/libfreetype.6.dylib Expected in: flat namespace dyld: Symbol not found: _FSPathMakeRef Referenced from: /usr/local/lib/freetype-2.2.1/lib/libfreetype.6.dylib Expected in: flat namespace [Sat Jul 12 17:56:41 2008] [notice] child pid 3368 exit signal Trace/BPT trap (5) ---------------------------------------------- Previous Comments: ------------------------------------------------------------------------ [2008-07-08 06:00:39] [EMAIL PROTECTED] Sorry, we don't support 3rd party tools like ZendDebugger, ZendCore, XCache or other tools affecting the runtime.

When I installed Zend Debugger 5.5.1 about a year and a half ago, it came with its own php.ini, and originally had a great deal of trouble getting it running. It had been compiled in 32 bit mode as best I understand it, so once I got everything working I posted a message on 4/29/2008 "Getting 32 bit ZendStudio Debugger to work with 64 bit Apache2 - PHP using MacPorts on Leopard" that provided explicit instructions on how to get it working. The message I posted on 4/29/2008 "Getting 32 bit ZendStudio Debugger to work with 64 bit Apache2 - PHP using MacPorts on Leopard" that provided explicit instructions on how to get it working, is no longer valid. In the later versions of OS X ZEND DEBUGGER DOES NOT require that you call : ---------------------------------------------------------------------- --------- RESTART THE 64 bit APACHE2 using the 32 bit mode ( 'arch -i386' ) : ---------------------------------------------------------------------- --------- shell> ~ $ sudo arch -i386 /opt/local/apache2/bin/apachectl start shell> ~ $ ps aux | grep httpd ---------------------------------------------------------------------- --------- ZEND DEBUGGER works fine using 64 bit mode : ---------------------------------------------------------------------- --------- shell> ~ $ sudo /opt/local/apache2/bin/apachectl start shell> ~ $ ps aux | grep httpd As a carry over from an old version of Zend Debugger 4.x (about 3-4 years old) my php.ini contained : ; [Zend] extension_dir=/Applications/Zend/ZendStudio-5.5.1/bin/php5 extension=pgsql.so $ which php ---> /opt/local/bin/php $ php --version ---> PHP Warning: PHP Startup: Unable to load dynamic library '/Applications/Zend/ZendStudio-5.5.1/bin/php5/pgsql.so' - (null) in Unknown on line 0 ---> Warning: PHP Startup: Unable to load dynamic library '/Applications/Zend/ZendStudio-5.5.1/bin/php5/pgsql.so' - (null) in Unknown on line 0 ---> PHP 5.2.6 (cli) (built: Jul 7 2008 15:05:26) ---> Copyright (c) 1997-2008 The PHP Group ---> Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies ---> with Zend Debugger v5.2.12, Copyright (c) 1999-2007, by Zend Technologies Originally when I tried I got the errors again : $ php inc_random_image_two.php > zippy.png ---> PHP Warning: PHP Startup: Unable to load dynamic library '/Applications/Zend/ZendStudio-5.5.1/bin/php5/pgsql.so' - (null) in Unknown on line 0 ---> Warning: PHP Startup: Unable to load dynamic library '/Applications/Zend/ZendStudio-5.5.1/bin/php5/pgsql.so' - (null) in Unknown on line 0 $ open zippy.png But when I opened zippy.png above the image worked. GOING BACK to the 'PHP Warning' : Even with the two lines below the [Zend] Apache and PHP seemed to work fine. I had seen the warnings several times in the logs but never figured out what to do about it, it turned out it was really simple : I have a php.ini that contains all my conf stuff, but ZEND DEBUGGER has its own php.ini, where it also has additional stuff, which is totally different than it used to be in the previous debugger version. ; [Zend] ; extension_dir=/Applications/Zend/ZendStudio-5.5.1/bin/php5 ; extension=pgsql.so Commenting them out solved the problem, and miraculously 'inc_random_image_two'.php below worked correctly. THIS time 'php --version' worked correctly also : $ php --version PHP 5.2.6 (cli) (built: Jul 7 2008 15:05:26) Copyright (c) 1997-2008 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies with Zend Debugger v5.2.12, Copyright (c) 1999-2007, by Zend Technologies NOW I tried calling 'random_image_sample.php' in Safari, and the image displayed correctly. The problem with 'imagettftext' dissapeared, or so I thought. The image displayed correctly as long as I do not use the ZEND DEBUGGER. If I use the debugger the line containing 'imagettftext' causes the debugger to exit without any warning, or error message. Its bizarre, because I've never seen the debugger exit this way. CONCLUSION : There appears that there were at least two or three issues causing this problem. ( 1 ) Bufoonery on my part for not resolving the 'PHP Warning' sooner. ( 2 ) The problem between 'imagettftext' and ZEND DEBUGGER. ( 3 ) 'imagettftext' did not work in 32 bit mode even without the ZEND DEBUGGER. I had also upgraded all the ports earlier today, but I don't believe they had anything to do with the image display problem. I put the code for the two sample pages on here again, in case they are helpful to others. <?php session_start(); ?> <!-- [4325] ( BEGIN ) filename : random_image_sample.php --> <HTML> <HEAD> <TITLE>Random image sample</TITLE> <META HTTP-EQUIV=\"Content-Type\" CONTENT=\"text/html; charset=iso- 8859-1\"> </HEAD> <BODY> <?php $errors=0; if(isset($_POST['Submit'])) { $number = $_POST['number']; if(md5($number) != $_SESSION['image_value']) echo '<h1>Validation string not valid!
