Description:
------------
Calls to imagettftext will always fail with no error on Leopard 10.5.2 when run under Apache 2 (bundled GD library).

The Apache error log reveals:
Break on __THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__() to debug.
[Mon Mar 24 16:12:05 2008] [notice] child pid 74505 exit signal Trace/BPT trap (5)

It is important to note that the code works as expected in the CLI version of PHP.

Reproduce code:
---------------
<?php
header("Content-type: image/png");
$im = imagecreatetruecolor(400, 30);
$white = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);
imagefilledrectangle($im, 0, 0, 399, 29, $black);
$font = '/[path to font]/Verdana.ttf'; // any font
imagettftext ($im, 10, 0, 10, 10, $white, $font, 'My Text');
imagepng($im);
imagedestroy($im);
?>

Expected result:
----------------
A black box with the words "My Text" in white letters

Actual result:
--------------
No output is produced
